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)

2700=2200(r+1)^5\\\frac{27}{22}=(r+1)^5\\\sqrt[5]{\frac{27}{22}}=\sqrt[5]{(r+1)^5}\\\frac{27}{22}^\frac{1}{5}=r+1\\r=\frac{27}{22}^{0.2}-1\\r=1.0418-1\\r=0.0418

r = 0.0418

Use a benchmark fraction to compare 7 10 ths and 5 12 ths. Explain how you found the answer
elixir [45]
<span>Benchmark fractions are created when we make two different fractions have the same numerator or denominator. In thisi case, we will produce the same denominator. The LCM of 10 and 12 is 60. So the fractions become 42/60 and 25/60. Since the fraction with the larger numerator has a larger value when the denominators are the same, 7/10 is larger than 5/12.</span>
