Your question states...
Sixteen -------> 16
divided by -------> /
the sum of x and 5 -----> x+5
is 12 ------> = 12
16/x+5 = 12
Answer D
The reason it is NOT answer A is because is says "divided by the sum of x and 5". In the order of operations, division happens before addition, so if it did not say "the sum of", then 16 divided by x (16/x) would happen before adding 5 (like in answer A). But is says "the sum of" so you have to do the addition first.
You would multiply 7 times 9 which would be 63 and then you would subtract that from 144 and come out with An awnser of 81

(5,38).
38=8(5)-2 is 38=40-2 and that's 38=38.
38=9(5)-7 is 38=45-7 and that's 38=38.
