The answer c
Hope I helped :)
Step-by-step explanation:
Solve for x by simplifying both sides of the equation then isolating the variable.
Exact Form:
x=1/3
Decimal Form:
x=0.333333333
Let the full marks be represented by = x
As given, 80% of x is 75
So,
x= 
x=93.75
Hence, full marks is 93.75
We can check also- 
=75
The answer is negative because, ( -81/-9) =(+9). -(+9) = -9. Maybe for got the - sign before the equation
So in order to compare, the measurements have to same units. So lets convert everything to feet.
George 2 yds = 6 ft Kelsey 68 inches = 5 ft 8"
Mariah 5 feet Brian 5 ft 10 "
George measured the tallest at 6'
Hope this helped.
