2700=2200(1+r)^5
2 answers:
Solve your equation step-by-step.
2700=2200(1+r)^5
Flip the equation.
2200(r+1)^5 = 2700
Divide both sides by 2200.
2200(r+1)^5 / 2200 = 2700 / 2200
(r+1)^5=27/22
Solve Exponent.
(r+1)^5=27/22
((r+1)5) ^1/5 = (27/22)^1/5 (Raise both sides to power)
r+1=1.041809
r+1−1=1.041809−1(Subtract 1 from both sides)
r = 0.041809
Check answers. (Plug them in to make sure they work.)
r = 0.041809 (Works in original equation)

Answer:
C) 20, 4
Step-by-step explanation:
X = 5y
2x + 5y = 60
substitute in 5y for x: 2(5y) + 5y = 60
10y + 5y = 60
15y = 60
y = 4
x = 5y
x = 5(4) = 20
