Solve the linear equation: 5 - x = (x/2)
Hi
5-x = (x/2)
5 = (x/2) +x
10 = x+2x
10 = 3x
10/3 = x
let's check :
5- 10/3 = 15/3 -10/3 = 5/3
(10/3) /2 =10/3 * 1/2 = 10/6 = 5*2/3*2 = 5/3
∠A and \angle B∠B are supplementary angles. If m\angle A=(2x+10)^{\circ}∠A=(2x+10) ∘ and m\angle B=(2x+2)^{\circ}∠B=(2x+2) ∘ , then find the measure of \angle A∠A.

Steve will roll a number cube, numbered 1-6, twice. What is the probability of rolling a number greater than 4, then
rolling an odd number?
Answer:
6/36 or 1/6
Step-by-step explanation:
To find the probability of rolling a number greater than 4, then rolling an odd number, you must multiply the probability of rolling numbers greater than 4 by the probability of rolling an odd number. In numbers 1-6, there are two number greater than 4: 5 and 6. The probability of an event is the specific factor over the total amount of results or objects. The probability of rolling a number higher than 4 is 2/6, or 1/3. In numbers 1-6, there are 3 odd numbers: 1, 3, and 5. The probability of rolling an odd number is 3/6, or 1/2. 3/6 times 2/6 is 6/36, and when simplified, it becomes 1/6.
20/3=2(w+2/3)
What’s the value of w
Answer: w=8/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20 /3 =2(w+ ( 2 /3 )
20 /3 =(2)(w)+(2)( 2 /3 )(Distribute)
20 /3 =2w+ 4 /3
Step 2: Flip the equation.
2w+ 4 /3 = 20 /3
Subtract 4/3 from each side: 2w+ 4 /3 − 4 /3 = 20 /3 − 4 /3
Divide both sides by 2: 2w/ 2 =16 3 /2
Answer w=8/3
Answer:
w=8/3

Find the mean of the following data set
73, 81, 51, 76, 89, 95, 88
Answer:
[tex]mean = \frac{(73 + 81 + 51 + 76 + 89 + 95 + 88)}{7} \\ = 79[/tex]
Answer:
79
Step-by-step explanation:
What is mean? The mean is the same as an average. To find the mean, add all the letters together. Then, divide this sum by the total amount of numbers.
Step One: 73+ 81+51 +76+ 89+ 95+88= 553
Step Two: Divide by numbers, in this case, there are 7: 553/7= 79.

Taylor had a bag of 28 marbles. 5 red, 9 blue, 8 yellow, and 6 black. If Taylor pulled out a yellow one and DID NOT put it back in. What is the
probability of pulling out a blue marble (SIMPLIFY YOUR FRACTION).
Blank 1:
Blank 2:
Answer: 1/3
Step-by-step explanation:
Number of red marbles = 5
Number of blue marbles = 9
Number of yellow marbles = 8
Number of and black marbles = 6
Total number of marbles = 28
If Taylor pulled out a yellow one and didn't replce it, there'll be 27 marbles left since one has been removed, then the probability of picking blue marbles will be:
= Number of blue marbles / Total marbles
= 9 / 27
= 1/3
The probability of picking a blue marble is 1/3.

Sam is a cashier at the local grocery store. He earns $8/hr and works there 10 hours per
week. Every week, he puts 75% of his money in a savings account so he can reach his goal
of having $1,000 as an emergency fund. School is starting in a few weeks and he wants to
buy some new supplies including a backpack, pens and notebooks, and more. He
estimates the total will be about $75.
T
Answer:
A. $80
B. $60
C. 4 Weeks
D. Sam might have to work more at his work or possibly lower the amount of money he needs to save.
Step-by-step explanation:
Hope this Helps!!
The number of weeks taken by Sam to save enough money is 17 weeks.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
a) Money Sam earns in one week = Money paid per hour * Number of hours per week
= 8×10
= $80
b) Money saved every week is
75% of 80
= 75/100 ×80
= 0.75×80
= $60
c) He can reach his goal of having $1,000 as an emergency fund.
Let the number of weeks taken by Sam to save enough money be x.
Now, 60x=1000
x=1000/60
x=17 weeks
d) School is starting in a few weeks and he wants to buy some new supplies including a backpack, pens and notebooks, and more.
He estimates the total will be about $75.
So, Sam has to work one week extra to purchase his needs for school.
Therefore, the number of weeks taken by Sam to save enough money is 17 weeks.

Suppose a study estimated that 61% of the residents of a community (with an
error range of 18 percentage points at 95% confidence) favor replacing the
playground equipment. Which of the following percentages of the
community's residents may favor replacing the playground equipment?
A. 82%
B. 54%
C. 72%
D. 95%
Finding the confidence interval, it is found that the percentages of residents that may favor replacing the equipment is be given by:
B. 54%.
What is a confidence interval?The interval is given by the estimate plus/minus the margin of error. The range is twice the margin of error.
In this problem, we have that:
The estimate is of 61%.Since the range is of 18%, the margin of error is of 9%.Hence the interval is given by:
(61% - 9%, 61% + 9%) = (52%, 70%).
Each of the values in the interval can be the percentage, hence option B is correct.

The population of village increases by 2% every year. The current population is 1000. What will be the population after 2 years?
Answer:
1040 approx
Step-by-step explanation:
Given data
Rate = 2%
Population= 1000
Time = 2 years
We can apply the expression below to find the population after 2 years
A= P(1+r)^t
Substitute
A= 1000(1+0.02)^2
A=1000(1.02)^2
A=1000*1.0404
A=1040.4
Hence the population is 1040 approx
