Solve the following word problem by creating an algebraic equation and solving for the unknown value.
Madison and Mackenzie made $87 selling girl scout cookies. Madison made $15 more than 2 times as much as Mackenzie made. How much money did Mackenzie make?
Answer:
2 equations were used : x + y = 87 and x = 2y + 15
Step-by-step explanation:
Defining variables:
Madison = x
Mackenzie = y
-----------------------------------
Here's what we know:
Madison and Mackenzie made $87 selling girl scout cookies (TOGETHER). Therefore: x + y = 87
We also know that Madison made $15 more than 2 times as much as Mackenzie made.
Therefore: x = 2y + 15
Now we can substitute the 2nd equation (x = 2y + 15).
This gives us (2y + 15) + y = 87
After solving (2y + 15) + y = 87, we get y = 24
Okay, so now we know Mackenzie sold $24 worth of girlscout cookies...
this is also known as y = 24
---------------------------------------------------------------------------------------------------------
If we were to find out how much madison made aswell, here's what we would do.
We will put y = 24 back into the original equation (x + y = 87).
x + 24 = 87
x = 63
Madison sold $63 worth of girlscout cookies.

A runner completed a 26.2-mile marathon in 210 minutes.
- Estimate the unit rate, in miles per minute. Round your answer to the nearest hundredth.
- Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth.
- Another runner says, "I averaged 10-minute miles in the marathon." Is this runner talking about the unit rate described in part (a) or in part (b)?
- Explain your reasoning.
Answer:
0.123 miles per min
8 mins per mile
The runner is talking about part (b)
Part a) is miles per minute and the runner said they did 10 minutes every mile same thing as minutes per mile or part b
Step-by-step explanation:
Since your doing per minute you do you do the amount of miles over the amount of minutes so you can see how many miles the runner went in each minute
And when doing per mile its the same idea you just minutes over miles now so you get for every mile the number of minutes.

ABC is a right triangle with vertices B (9, 4) and C (3, 9).
What are the coordinates of vertex A?
Enter your answers in the boxes.
Answer:
A (3, 4)
Step-by-step explanation:
A has to be positioned horizontally along B. This means its x coordinate is the same as x-coordinate of B which is 4
A also has to be positioned vertically below C. This means its y coordinate is the same as the y-coordinate of C. So y-coordinate of A is 3
So coordinates of A are (3, 4)

Answer: There are between 9 and 10 ounces of fluid in container B.
Step-by-step explanation: There are between 9 and 10 ounces of fluid in container B. To find the number of ounces in container B, divide the number of ounces in container A by 8. This gives 76 / 8 = <<76/8=9.5>>9.5 ounces. Since 9.5 is between 9 and 10, the correct answer is "There are between 9 and 10 ounces of fluid in container B."
Two square-shaped fields are next to each other. The perimeter of each field is 28 feet. The two fields are joined together to form a single rectangular field. What is the perimeter of the rectangular field?
A. 42 feet
B. 49 feet
C. 56 feet
D. 63 feet
Answer: A. 42 feet
Step-by-step explanation:
If a square has a perimeter of 28 feet, then each side would be 7 feet long because a square has 4 equal sides.
So if they are joined together to make a rectangle, the short side would be 7 feet long and the longer side would be 14 feet long.
You then add all the sides together so:
7 + 7 + 14 + 14 = 42 feet
Find the percent equivalent 6 over 15.
Answer:
40%
Step-by-step explanation:
Because 15 is the denominator in 6/15, we might change the fraction to make 100 the denominator. In order to do it, 100 is divided by the numerator:
=40/100
Now that we know our fraction is 40/100, we can see that 40% of 6/15 is represented as a percentage.
therefore youre answer would be 40%
Answer:
40%
Step-by-step explanation:
6/15 = 40/100

I WILL GIIVE BRAINIEST AND THANKS
Answer: -22.25
Step-by-step explanation:
I think this is how to do it but the way you explained the expression was slightly confusing but I set it up like this:
(3/10)^2 - 17 + (-7/ | 4.3 - 7.8 |) x 2.67
then when I simplified the expression I received an answer of -22.23 which is close to one of the given answers of -22.25
