The answer is 63 because (6+3) is 9 so 7(9) is 63
5x-3-7＝9+2x-16
5x-10＝2x-7
5x-2x＝-7+10
3x＝3
X＝1
-7.89, -5.23, -5.22, 34.98, 51.02, 51.22
Lets break it down:
(Rational numbers consist of whole, numbers, integers, and fractions)
Negatives come after 0, so the greater the number gets, the less value it has, opposite of positive numbers.
So since -7.89 is the greatest negative number, it will have the least value.
Hope this helps!
