15x + 10 = 100

Maddie's equation
15x - 10 = 100

Answers

Answer 1

     +10      +10

15x=110

/15     /15

x=7 1/3

MADDIE IS RIGHT

this is because she said 7 ans=d you cannot buy 1/3 of a shirt.

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.

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

Hope this makes sense!

If you know US Customary, you will recognize that in each foot, there is 12 inches. Answer a: 12(3) is equal to 36, 12(6) is equal to 72, and 12(9) is equal to 108. Through the process of elimination, Row 3 should not be 94 inches = 7 feet; it would be 84 inches. Hope this helps!

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.
