how to check:-17=-3x-2
Answers
Answer: x=5
Step-by-step explanation:
To solve this equation, we have to get the x alone. To cancel out the -2 on the right side, you will add 2 to both sides of the equation since -2 and 2 cancels out. Now you have -15=-3x. Now you will divide by -3 on both sides since the -3 in the equation is being multiplied by x. -15 divided by -3 equals 5. Therefore x=5.

A gardener uses a total of gallons of gasoline in one month. Of the total amount
of gasoline, was used in his lawn mowers. How many gallons of gasoline did the
gardener use his lawn mowers in one month?
Answers
Answer:
D. 36.9
Explanation:
three-fifths of 61.5 is 36.9!
Answer:
D. 36.9
Step-by-step explanation:
The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!
The table shows the results of 500 experiments. Each experiment involved one person choosing one card from each of two identic decks of cards, labeled 1 through 5. What is the experimental probability of a person choosing a 2, then a 3? Express the answer as percent. ( I really need help with this, I tried looking at my notes and my brain literally can’t function )
Answers
Unfortunately, I cannot see the table you mentioned. However, I can explain how to calculate experimental probability and apply it to the given situation.
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted. In this case, the event is a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5.
Let's say we conducted 500 experiments, and in 50 of those experiments, a person chose a 2, then a 3. Then the experimental probability of choosing a 2, then a 3 is:
Experimental probability = (Number of times the event occurred) / (Total number of experiments) = 50 / 500 = 0.1
To express this as a percent, we simply multiply by 100:
Experimental probability as percent = 0.1 x 100% = 10%
Therefore, the experimental probability of a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5, based on 500 experiments, is 10%.

Nathan is using the random number string below in a simulation. He wants to determine how many people he has to meet before he finds one that is left-handed.
1 5 8 9 7 8 2 3 6 7 0 5 6 5 9 3 7 0 9 4
He lets each number in the string represent a person, with 0 representing left-handed people and 1 through 9 representing right-handed people. According to the simulation, how many people does he have to meet until he finds the first left-handed person?
Answers
Answer:11people
Step-by-step explanation:
For this question, ignore all numbers that are not 0 to start with, as 0 is the only number that shows you an individual who is left-handed. Now, take a look at where 0 is. How many numbers do you see before it? There are 10 numbers before 0, and if you add 1 more, there are 11 in total. The first left-handed person is the 11th person Nathan will meet.

Describe a rule for determining how much the store charges based on the number of turkey subs delivered.
Answers
The rule for determining how much the store charges based on the number of turkey subs delivered will depend on the pricing structure that the store uses. One possible rule is a linear function, where the cost of each turkey sub is a fixed amount and the total cost is proportional to the number of subs delivered.
For example, if the store charges $5 for each turkey sub, the rule could be:
Total cost = $5 per sub * Number of subs delivered
So if the store delivers 10 turkey subs, the total cost would be:
Total cost = $5 per sub * 10 subs = $50
If the store delivers 20 turkey subs, the total cost would be:
Total cost = $5 per sub * 20 subs = $100
This rule assumes that the cost per sub remains constant regardless of the number of subs delivered. However, in reality, the cost per sub may vary depending on factors such as the cost of ingredients and labor, and the store's desired profit margin.
5 Figure N is a rectangular prism that has twice the volume of figure M. How many layers and how many cubes in each layer could there be in figure N?
Answers
The number of layers of M and in N in 2
How many layers and how many cubes in each layerWe do know that Figure N has twice the volume of Figure M. Since both figures are rectangular prisms, their volumes can be calculated using the formula:
Volume = length x width x height
Let's say that Figure M has a length of L, a width of W, and a height of H.
Then its volume is:
Volume_M = LWH
Since Figure N has twice the volume of Figure M, we can write:
Volume_N = 2 x Volume_M
Substituting the formula for Volume_M, we get:
Volume_N = 2LWH
This means that two layers of M and in N
The number of cubes cannot be determined with the available information

Step-by-step explanation:
To find the area of a rectangle, there is a formula:

So, we know the length is 7ft, and the width is 6/10.
Substitute in the 2 values:
[tex]A=7(6/10)[/tex]
From here, you can go 2 ways:
1) Change 6/10 to a decimal, 0.6
-Then, multiply 7 x 0.6
- This equals 4.2, which as a fraction is 4 1/5 or 21/5
2) Turn 7 into a fraction, 7/1 and multiply the numerators and denominators:
- 7/1 x 6/10 = 42/10 = 21/5

Three park rangers had to report on the ways visitors use their facilities. Each ranger surveyed a sample of park visitors. Determine whether or not each sampling described is random or biased.
Answers
Answer:
To determine whether a sampling is random or biased, we need to know how the sample was selected. Here are three possible scenarios:
Ranger 1 stands at the entrance to the park and surveys the first 100 visitors who arrive.
This sampling is biased, as it only includes visitors who arrived early in the day. Visitors who arrive later in the day may have different characteristics or behaviors, so this sample may not be representative of all park visitors.
Ranger 2 selects every 10th visitor who enters the park and surveys them.
This sampling is random, as every 10th visitor is selected without bias. This method is called systematic sampling.
Ranger 3 surveys visitors who are leaving the park on a rainy day.
This sampling is biased, as visitors who come to the park on a rainy day may have different motivations or behaviors than visitors on a sunny day. This sample may not be representative of all park visitors.
In summary, sampling methods that are random, such as systematic sampling, are preferred over biased sampling methods in order to obtain a representative sample of the population of interest.
Answer: Depending on the situation
Step-by-step explanation: For a sample to be random, everyone/thing has to have an equal chance of getting selected. Ex. One of the park rangers asked everyone in one part of the park. - This example would be biased because the people who weren't in that part of the park had less of a chance of being picked

The cell phone company allows all users 450 text messages a month. Any text messages over the allowed amount are charged $0.25 per message. Craig only has $26 extra to sped on his cell phone bill. how many messages can he go over the allowed amount for the month without breaking his budget of $26? Let p represent the amount of text messages Craig can go over.
Inequality: ___________
Craig can send and receive ______________ extra text messages without breaking his budget of $26
Answers
Let's first find the total cost of the text messages Craig can send in a month. Craig is allowed to send 450 text messages without any additional charges. If he sends more than that, he will be charged $0.25 per message. Let's say he sends x additional messages over the 450 allowed:
Cost of additional messages = $0.25 * x
So, the total cost of Craig's text messages in a month is:
Total cost = Cost of allowed messages + Cost of additional messages
Total cost = $0 + $0.25x
Total cost = $0.25x
We know that Craig has a budget of $26 for his cell phone bill. We can set up an equation to represent this:
Total cost ≤ $26
Substituting the expression for the total cost of Craig's text messages, we get:
$0.25x ≤ $26
Dividing both sides by $0.25:
x ≤ 104
Therefore, Craig can go over the allowed amount by at most 104 text messages without breaking his budget of $26.
Answer: he can go over by 104
Step-by-step explanation:Total cost = $0 + $0.25x
Total cost = $0.25x
Total cost ≤ $26
Substituting the expression for the total cost of Craig's text messages, we get:
$0.25x ≤ $26
Dividing both sides by $0.25:
x ≤ 104
Therefore, Craig can go over the allowed amount by at most 104 text messages without breaking his budget of $26.
