Step-by-step explanation:

We are given the expression to be simplified:

Let us take common a term with a power of 5 from the numerator and the denominator of the given expression.

We know that:

Let us use it to solve the powers of 5 in the given expression.

we can write:

The given expression becomes:

Taking common from the numerator and

Taking common from the denominator

The answer is:

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
