Use a unit rate to find the unknown value.

1: 40/8 = 45/?

2: 42/14 = ? /5

3: ? /2 = 56/8

4: ? /4 = 26/13

answer all of the questions, and lable the answers to the questions you are answering.
example:

1: 40/8 = 45/1238195

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
