The area of a rectangle is 7.35m squared . The width is 2.1 m.
What is the length?

this is easy. so take the equation used for finding the area (A = LW). you then place the sizes in the proper places (making 7.35 = 2.1L). now all you have to do is divide 7.35 (area) by 2.1 (width) to get your length (3.5).

Step-by-step explanation:

7.35 = 2.1L

7.35/2.1 = 3.5

L = 3.5

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
