His sister is 7.895 feet tall.
5x - 2x = 63 + 57
3x = 120
x = 40
Because if u divide 3 by 4 you get .75 which is out of 100 %
This is a problem involving the subtraction of two functions f(x) and g(x):
<span>if f(x)=3x-1 and g(x)=x+2, find (f-g)(x). In other words, find:
</span><span> f(x) = 3x-1
-{g(x) -(x+2)
-----------------
f(x) - g(x) = 3x - 1 - x - 2 = 2x - 3 (answer)</span>
