If five times a number plus two is 17, what is the number?
a. 7
b. 5
c. 3
d. 2

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.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
