Step-by-step explanation:
Mean of the 5 is the average
lets solve for what score gets 80
and lets say last score is x
so
(sum of scores)/4=80
(62+75+90+x)/4=80
(227+x)/4=80
times 4 both sides
227+x=320
minus 227 from both sides
x=93

Answer:
9ab - 9a +1
Step-by-step explanation:
first, we can distribute the negative sign to the second set of parentheses.
-(-4ab + 5) becomes + 4ab - 5
now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5
5ab + 4ab - 9a - 4 - 5
= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.
