Question

shen baked b cookies. his family ate 11 of them. using b, write an expression for the number of cookies that remained.

Answer 1

Explanation:

So, lets write out the equation you have right now.

B - 11 = ?

You can have B be whatever you want. It must be higher than 11 (unless your teacher or whoever your guardian is allows negative numbers). In this case, I will use 15.

B = 15

15 - 11 = ?

Solve the equation and you get 4. Simple!
