Cole is finding the quotient of 78 + 4. He creates this model to help him solve the division problem

Which statements are true about Cole's work? Check all

that apply

D

Cole's model correctly shows that the quotient of 78 + 4

is 12 with a remainder of 30.

Cole has not finished modeling this problem

Cole needs to add another ten block to his model to

show 78

Cole should have divided the 3 extra tens blocks into 30

ones blocks

A complete model would show the quotient of 78 -4 is

19 with a remainder of 2

1.4

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
