635/72=-5/2(-11/4+x)
distribute
635/72 = -5/2 * -11/4 - 5/2x
635/72 = 55/8 -5/2 x
multiply each side by 72 to clear the fractions
72*635/72 = 72*(55/8 - 5/2 x)
distribute
635 = 72* 55/8 - 72* 5/2 x
635 = 495 - 180x
subtract 495 from each side
140 = -180 x
divide by -180
-140/180 = x
-14/18 =x
-7/9 =x
Answer:
2n - 4
Step-by-step explanation:
expand brackets
8n - 4 - 6n
collect like terms
2n - 4
All you have to do is plug in 4 where n is
In other words n = 4
So...
F(n) = 5^n
F(4) = 5^4 or (5 x 5 x 5 x 5)
F(4) = 625
