Divide using long division
1. (5^4 + 3^3 + 2 − 5) ÷ ( − 11)
2. (2^4 − 3^2 − 12 − 7) ÷ ( − 2)
3. (4 4 + 2 3 + 2 − 4) ÷ ( − 3)

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
