15 units

Step-by-step explanation:

1. Find the corresponding lengths of the triangles.

9/x = x/ (9+16)

9/x = x/25

2. Solve for x.

Multiply both sides by x.

9 = x²/25

Multiply both sides by 25.

225 = x²

Square root both sides to solve for x.

√225 = √x²

x = 15

5050 i think

step-by-step explanation:

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
