Question

Please Help!

Answer 1

For this one, the best way to answer is to use the question and it will guide us to the answer.

First, you can eliminate two choices:

the problem states that a number minus ten and nine

so you can eliminate B and D because it is 10 minus a number.  In math, you can be picky and take the question exactly.

Then, look at the last part, "when decreased by seven."  So now look between A and C and see which one is decreasing by 7.  Based on that C would be your answer

C) 9(x-10) -7 = 50

Hope this helps!
