Evaluate s5 for 300 + 150 + 75 + … and select the correct answer below.

581.25

Step-by-step explanation:

Use the formula for when the last term is unknown. It is .

For this equation (sum of the numbers)= , (amount of first term) = 300, r (ratio)= .5, and n (number of terms) = 5. Knowing this, we plug them into the equation. It would look like: .

First, we solve the exponents. 0.5 to the fifth power = .03125. Now multiply it by the nearest number in parentheses, which is 300. You should get 9.375.

Now, subtract that from 300. 300 - 9.375 = 290.625. Your numerator is 290.625.

Simplify your denominator. 1 - 0.5 = 0.5.

Divide.

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
