Question

@iGreen 
7. x/4=12/6
a. x=6
b. x=12
c. x=8
d. x=48

8. 9=m-4
a. m=36
b. m=13
c. m=5
d. m=9/4

9. j-3=-7
a. j=-10
b. j=21
c. j=-4
d. j=4

igreen · Answer

x/4 = 12/6

Multiply 4 to both sides:

12/6 * 4 = 8

x = 8

igreen · Answer

9 = m - 4

Add 4 to both sides:

4 + 9 = 13

m = 13

igreen · Answer

j - 3 = -7

Add 3 to both sides:

-7 + 3 = -4

j = -4

10. you need to make 18 cupcakes for a birthday party. you have already made 11. how many mpre cupcakes do you need to make? write and equation and solve

igreen · Answer

You need 18 cupcakes.

You have already made 11.

x + 11 = 18 is your equation.

To solve it, subtract 11 to both sides.

18 - 11 = 7

x = 7

So you need to make 7 more cupcakes.
