8 = 23 - 5w
Solve for w

Step-by-step explanation:

8 = 23 - 5w

subtract 23 from both sides to cancel out 23

-15 = -5w

divide both sides by -5 to isolate w

3 = w, dividing a negative by a negative will result in a positive

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

i dont understand the question? ?
