Find three consecutive even integers such that the sum is of the least and the middle is 48 more than the greatest

50, 52, and 54

Step-by-step explanation:

The three even integers are x, x+2, and x+4.  The sum of the least two is 48 more than the greatest:

x + x+2 = x+4 + 48

2x + 2 = x + 52

x = 50

So the three integers are 50, 52, and 54.

17 1/3

step-by-step explanation:

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
