Question

Silas took 13 bags of glass to the recycling center. He still has 11 bags of plastic to take to the recycling center. Which equation could be used to find x, the total number of bags of glass and plastic Silas will take to the recycling center?
A.) x - 13 = 11
B.) 13 - x = 11
C.) x - 11 = -13
D.) x + 13 = 11

Answer 1

The answer is A, since the total is 13+11 so x-13=11 is correct.

Answer 2

If im not mistaking Silas has already taken the bags of glass already. So you took it out the equation and you have 11 bags of plastic left. Which is the only one that has a -13 and it equating 11 is A. Let my know if I’m wrong.
