A cell phone company has a basic monthly plan of 40 pulse .45 for any minutes used over 700 before receiving his statement Jhon saw he was charged a total of 48.10 write and solve an equation to determine how many minutes he must have used during the month

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

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
