If 40 men working on a U. S. government project can complete the job in 100 hours, how many men would be required to complete the job in 80 hours?

50

Step-by-step explanation:(40x100):80

50 workers

Let the ratio be

(40×100):80

= 400/80

= 50

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
