k - 4.5 = 9.8

addition property of equality

Step-by-step explanation:

k - 4.5 = 9.8

Add 4.5 to each side using the addition property of equality

k-4.5 +4.5 = 9.8+4.5

k = 14.3

the mean and mad

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
