Can someone help me with 8-grade math homework, please
Answer:
so y=7.25x+9.99 where y is the total money they spend, and the x is the total number of they want to bought jersey which is 20,
So here it's equation:
y=7.25(20)+9.99
y= 145+9.99
y=154.99, therefore the total is 154.99
and the second one is find and explain the mistake
the y values is the mistake when you equate the number of x to the equation given so the true answer of that table if you use the equation is:
X Y

What is the answer 38 + 7k = 8(k + 4)
pls give me an answer not a link so pls this is the last of my points
Answer:
[tex]k=6[/tex]
Step-by-step explanation:
We can distribute the right side to get [tex]38+7k=8k+32[/tex].
We can subtract [tex]7k[/tex] from both sides to get [tex]38=k+32[/tex].
We can subtract [tex]32[/tex] from both sides to get [tex]6=k[/tex].
So, the answer is [tex]\boxed{k=6}[/tex] and we're done!
The solution to the equation 38 + 7k = 8(k + 4) is k = 6.
We can begin by simplifying both sides of the equation in order to find the solution to the equation 38 + 7k = 8(k + 4):
38 + 7k = 8k + 32
Next, we can separate the constant terms from the variable terms by placing them on opposite sides of the equation:
7k - 8k = 32 - 38
Simplifying even more
-k = -6
We can multiply both sides of the equation by -1 to remove the negative sign:
k = 6
Hence K = 6 is the answer to the equation 38 + 7k = 8(k + 4).

Step-by-step explanation:
This can be calculated correctly using BIDMAS. This stands for Brackets, Indices, Multiply, Divide, Add, Subtract. Using BIDMAS will allow us to know what order to answer the question in.
In BIDMAS, Divide comes before Add, so we know to do this part first. So we do 8 divided by 2 which is 4.
The next part of our question is to add 6, so we do 6+4=10. So, 10 is the final answer.

A line passes through the points (-5, 2) and (10.-1). Which is the equation of the line?
Answer:
y= -1/5x + 1
Step-by-step explanation:
When looking for a line between two points, you want to use the following formula: (y2-y1)/(x2-x1) which finds your distance between points for the y and x coordinate to solve for your slope. y1 is the y coordinate from the first given point and x1 is the x coordinate from the first given point as well. this would go the same for x2 and y2 for the second given equation.
Next, we plug in our values so that we get (-1-2)/(10-(-5)). This will then lead us with -3/15 which simplifies to -1/5. This is our slope. Now that we have our slope we can rule out every option except the first for the answer. However, if we want to look for the entire answer we need to plug in one of our given values in the formula we have: y=-1/5x.
So to find the y-intercept, we can plug in any of the given coordinates so we can fo (10,-1) so that -1=-1/5(10)+b (b what added because we are putting the equation in slope-intercept, therefore we need to find the value b.) So we are left with -1=-2+b now we want to isolate b by adding 2 on both sides to cancel -2 and get 1=b. This would leave us with the equation y=-1/5x+1.

Aimee went to a stationary shop. She purchased 2 packs of red pens, 4 packs of black pens, and 3 packs of blue pens.
The cost of each pack of pens was $2.50. Which expression shows the total amount Aimee spent on the pens?
A ($2.50 x 2 x 4x3)
B $2.50 x (2+4+3)
C($2.50 x 2) + 3+4
D (52.50 +2 +4+3)
Answer:
A.
Step-by-step explanation:
The answer is B.
Each pack costs 2.50, so this means we can add all of our packs brought together, before multiplying. (2+4+3)=7. So our final equation should be 7 x 2.50 ,therefore B is our correct answer.

Mr. Webster is buying carpet for an exercise room in his basement. The room will have an area of 230 square feet. The width of the room with have 12&1/2 feet. What is the length?
PLEASE DO NOT JUST GIVE THE ANSWER, (I could have done that myself) PLEASE SHOW WORK ON HOW YOU GOT THE ANSWER.
Thanks!
Answer: 18.4 ft
Step-by-step explanation:
Area= L x W
230= 12.5 x L (Divide both sides by 12.5 to get L)
L= 18.4 ft
Answer:
The length of the room is 18 2/5 feet.
Step-by-step explanation:
The formula for finding the area of rectangles is A = l · w
Since the area and width is given to you, we can substitute that in the formula:
230 = l · 12 1/2
Now we convert the 12 1/2 to an improper fraction so it is easier to solve.
Here's how you convert a mixed number to an improper fraction:
12 · 2 = 24
24 + 1 = 25
and put 25 over the original denominator
= 25/2
Now you can add that to the equation...
l · 25/2 = 230 (I put 230 on the right side because that is how I am used to solving equations, but you can leave it on the right side as well. It is up to you)
To get rid of fractions, multiply by the reciprocal (Basically you flip the fraction so that the numerator becomes the denominator and the denominator becomes the numerator) on both sides
25/2 · 2/25 cancels itself out
and
230/1 · 2/25...
230 · 2 = 460
1 · 25 = 25
So you would get 460/25
Thus, we end up with:
l = 460/25
Divide 460 by 25 and you get 18.4...
Technically 18.4 is the answer but in decimal form.
If you want it in fraction form, just take 0.4 and put it over 10 because 0.4 is in the tenths place. 4/10 simplifies down to 2/5...
Therefore, the answer is 18 2/5 feet.

Susan and Jim both babysit. Susan earns $15 for 2 hours and $30 for 4 hours. Jim’s charges are calculated using the equation t=7h+10 (t is the total and h is the hours) which statement is true
A.) Jim charges $7.00/hour, which is higher than Susan’s hourly rate
B.) Jim charges $10.00/hour, which is higher than Susan’s hourly rate
C.) Susan charges $7.00, which is equal to Jim’s hourly rate
D.) Susan charges $7.50, which is higher than Jim’s hourly rate
Please answer as soon a possible
Answer:
D.
Step-by-step explanation:
7h is the amount of money Jim makes per hour. You can find the amount of money Susan makes by dividing the amount she made to the hours:
15/2 = 7.50
Susan charges $7.50, which is higher than Jim's hourly rate. which is the correct answer would be a statement (D)
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
To find the hourly rate for Jim, you can plug in different values for h (the number of hours) in the equation t = 7h + 10 and solve for t (the total). For example, if h = 1, then t = 7(1) + 10 = 17. This means that if Jim babysits for 1 hour, he charges $17.
If you divide the total amount that Jim charges by the number of hours he works, you get his hourly rate. In this case, the hourly rate is t/h = 17/1 = $17/hour.
To find Susan's hourly rate, you can divide the total amount that she charges by the number of hours she works. For example, if Susan babysits for 2 hours, she charges $15, so her hourly rate is $15/2 = $7.50/hour. If Susan babysits for 4 hours, she charges $30, so her hourly rate is $30/4 = $7.50/hour.
Since Susan charges $7.50/hour, which is higher than Jim's hourly rate of $17/hour, the correct statement is D.) Susan charges $7.50, which is higher than Jim's hourly rate.

How do I get the x and y intercepts to graph this equation?
Y=-1/2x-3
Answer: x intercept is (-6,0) and y intercept is (0,-3)
Step-by-step explanation: the y intercept is when x=0. the x intercept is when y=0.
to solve this for the y intercept, we set x=0 in the equation y=-1/2x-3. so it would be y=-1/2(0)-3 therefore y= 0-3 and y=-3. the y intercept is (0,-3)
to solve for the x intercept, we set y=0. we plug it into the equation y=-1/2x-3 so 0=-1/2x - 3. this means we can change the sign of -1/2x from negative to positive and move it to the other side. so 1/2x=-3 to solve for x, we divide both sides by 1/2 so x=-6. so the x intercept is (-6,0)
