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)
N+d=34
.05n+.10d=2.60
Solve by substitution
n=34-d
.05(34-d)+.10d=2.60
1.7-.05d+.10d=2.60
.05d=.90
d=18 dimes
18+n=34
n=16 nickles
Answer:
x= -15
Step-by-step explanation:
Divide to both sides by -5 to isolate the variable.
<u>-5x</u>=<u>75</u>
-5 -5
x= -15
This gives you the answer of x= -15.
