Write the expression as a cube of monomial:

27x^12

Step-by-step explanation:

ax=axn to rewrite

3√27x12 as (27x12)1/3

to rewrite

3√(3x^4)3

Pull terms out from under the radical, assuming real numbers.

3X^4

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
