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.

Row 4 should show 9 feet is equivalent to 104 inches.
Answers
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

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?
Answers
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?
Answers
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.

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
