Use the image to answer the question

A = 140 in²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

here b = 20 and h = 14 , then

A = × 20 × 14 = 10 × 14 = 140 in²

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
