7. A polygon has vertices at F(-5, 2), G(-3, 2), H(-3, 4), |(1,4), K(1, 1), L(4, 1), M(4, -2), N(6, -2), P(6, -3), and
Q(-5, -3). Graph the figure on the coordinate plane.
Then find the area and perimeter of the figure.

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
