Question

If five times a number plus two is 17, what is the number? A. 7 B. 5 C. 3 D. 2

Answer 1

We can't tell where your parentheses are, so we don't know if you said 5 (x+2) = 17 or (5x+2)=17. ... If it's the first one, then x+2=17/5 and x=7/5 or 1.4. / / / If it's the second one, then 5x=15 and x=3. I guess it must be the second one, because 1.4 is not one of the choices. Ah the sleaze of math by multiple choice.

Answer 2

C=3
because 5 times 3 + 2+17
