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?
Answers
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.

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
Answers
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

y = -2x - 2
Step-by-step explanation:
x=x coordinate (-2 in this case)
m=slope (-2 in this case)
b= y int. (we dont know the number because it doesn’t label it so we just put the letter and you can solve for b if the question tells you so)
so the answer is
y=mx+b (slope int. form)

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.
Answers
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.

If you are planning on leaving 20% tip to the waiter and your meal costs $89.95, how much will you pay all together?
Answers
Answer: $107.94
Step-by-step explanation: The bill cost $89.95 with a tip amount of 20% you would end up spending $107.94 if you are not splitting the bill
Answer: 107.94: The total you pay is 107.94
Step-by-step explanation:
Total before the tip is 89.95
20% of 89.95 is equivalent to 0.20 x 89.95, which equals 17.99
add this tip, 17.99, to the price of the meal, 89.95.
17.99+89.95=107.94

Find the percent equivalent 6 over 15.
Answers
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

Answers
Answer:
-1.8 < 1 2/3 < 1.45 < 1- 3/8 < 9.3
Step-by-step explanation:
-1 2/3= -1.67 min
-1 3/8 = -1.375 min
so 7he least to greatest is
-1.8 < 1 2/3 < 1.45 < 1- 3/8 < 9.3
The ordered list from least to greatest is -1.8 < -1 2/3 < -1.45 < -1 3/8
What is a mixed fraction?
A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder.
So, a mixed fraction is a combination of a whole number and a proper fraction.
According to the given question:
Gina's relative time list is [tex]-1\frac{2}{3}[/tex] , -1.45, -1.8, [tex]-1\frac{3}{8}[/tex]
Converting mixed fractions to decimal forms to make comparison easy.
-1 2/3 = -1 + 2/3 = - 1.6 min
-1 3/8 = -1 + 3/8 = -1.375 min
Hence the new list is - 1.6, - 1.45, - 1.8, - 1.375
Arranging from least to greatest as follows
-1.8 < - 1.6 < - 1.45 < - 1.375
- 1.8 < -1 2/3 < -1.45 < -1 3/8

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.
Answers
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)
Write an exponential function to model the data in each table. Identify the growth or decay factor. (23) Picture
Answers
The model of the exponential functions show that
23: table 1 is a decay with a rate of 50%24. tables 2 is a growth with a rate of 10%How to write exponential function to model the data in each tableConsidering the given problem, f(x) = a(b)^x
the starting = a
the base = b
the exponents = x
23. Table 1
At x = 0
f(x) = a(b)^x
(b)^0 = 1
solving for a
4 = a * (b)^0
4 = a
At x = 1
f(x) = a(b)^x
(b)^1 = b
substituting known variables
2 = 4(b)^1
b = 2/4
b = 0.5
for decreasing rate, b = 1 - 0.5 = 0.5
rate, r = 50%
24. Table 2
At x = 0
f(x) = a(b)^x
(b)^0 = 1
solving for a
100 = a * (b)^0
100 = a
At x = 1
f(x) = a(b)^x
(b)^1 = b
substituting known variables
110 = 100(b)^1
b = 110/100
b = 1.10
for increasing rate, b = 1 + r = 1.10, r = 0.10
rate, r = 10%
The base is what determines exponential growth or decay
