A battery's is changed. The percentage of the battery’s capacity that is changed as a function of time (in minutes) is graphed.

What was the battery’s charging level when the charging began ?

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

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
