Answer:
12=3x-6 is 6
16=4x+8 is 2
4z+8=40 is 8
5x-7=38 is 9
-3x-9=24 is -11
Step-by-step explanation:
for 12=3x-6 you would get x by itself so first you add the 6 to the 12
you get 18 then you try to get the x by itself so you divide 3x by 3 and divide 18 by 3 as well. So you end up with 6=x. Repeat with every problem

Serena is building a bookcase. She cuts two pieces of wood from one board. One piece is 1 7/8 feet long and another is 3 1/2 feet long. What is the total change in the length of the original board?
Answer:
43/8 feet
Step-by-step explanation:
The total change is the sum of the length of two boards she cut.
First board length is 1 7/8th feet. Let's change to improper fraction:
1 7/8 = 15/8 feet
Second board lengrh is 3.5 feet, or 3 1/2 feet. Let's change to improper fraction:
3 1/2 = 7/2 feet
Let's add the two:
The change in original board is 43/8 feet

A ribbon is 5 4/5 yards long. Mae needs to cut the ribbon into pieces that are 4/5 of a yard long. How many pieces of ribbon can she cut?
The answer is 7 pieces.
If you divide 5.80 (5 4/5) by 0.80 (4/5), you get 7.25. Since Mae probably doesn't want to use a piece of ribbon smaller than the others she will only cut 7 pieces.
Answer:
7
Step-by-step explanation
5 4/5 = 5/5, 5/5, 5/5, 5/5, 5/5, 4/5
so five 5/5 - 1/5 each = 4/5, 4/5, 4/5, 4/5, 4/5 so we now have five 4/5 + the 4/5 we had at the beginning so we have six 4/5 then add all of the 1/5 we took away from all of the 5/5 so 1/5 x 5 = 5/5 = 4/5 Remainder 1/5 so we now have seven 4/5 and an extra 1/5
so, in conclusion, Mae can cut seven pieces of ribbon.

After 10 weeks, how much money would William have in his bank account? Show your work.
Answer:
f(x)=10x+5
Step-by-step explanation:
Answer:
$140

Use the data in the table to find the rate of change in the length of baby girl Grace. (2 points)
Answer: Baby Girl Grace grows 3/4 inch every month.
Step-by-step explanation:
Y= (y_2 - y_1)/ (x_2 - x_1)
Y= (29-26)/(16-12)
Y= (3/4)
The rate of change of height of baby girl is 0.75 inches per month.
What is Rate of change?A value that results from dividing the change in a function of a variable by the change in the variable velocity is the rate of change in distance with respect to time.
Here, from the given table;
At 4th month, the length of baby girl = 20 inches
at 30th month, the length of baby girl = 39.5 inches
x₁ = 4, y₁ = 20
x₂ = 30 y₂ = 39.5
Now,
Rate of change of height = (y₂-y₁) / (x₂ - x₁)
= (39.5 - 20) / (30 - 4)
= 19.5 / 26
= 0.75
Thus, the rate of change of height of baby girl is 0.75 inches per month.

One of the rows in the table has an error and does not have the same ratio as the other rows.

Which explains how to correct the error in the table?
Row 1 should show 3 feet is equivalent to 32 inches.
Row 2 should show 6 feet is equivalent to 66 inches.
Row 3 should show 7 feet is equivalent to 84 inches.
Row 4 should show 9 feet is equivalent to 104 inches.
Answer:
Row 3 should show 7 feet is equivalent to 84 inches.
Step-by-step explanation:
First divide 36 and 3 to find the constant proportion. Which you get 12
Now multiply 12 x 3 , 12 x 6, 12 x 7, and 12 x 9
You should be able to find the incorrect answer which is row 3
12 x 7 actually equals 84 not 94

A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft)
20 30
50 75
80 120
120 ? Which statement correctly explains how to find the distance traveled after 120 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. 20 multiplied by 6 is 120, so you can multiply 30 times 6 to find the distance. 30 multiplied by 4 is 120, so you can multiply 20 times 4 to find the distance.
Answer:
i think its C
Step-by-step explanation:
Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.
