I don't know exactly what needs to be answered, but I have till the end of the day to get most of this done, so please help-​

TEF = EGF + EFG

12x - 2 = ( 8x + 17 ) + ( 25 )

12x - 2 = 8x + 17 + 25

12x - 2 = 8x + 42

Add both sides 2

12x - 2 + 2 = 8x + 42 + 2

12x = 8x + 44

Subtract both sides by 8x

12x - 8x = 8x - 8x + 44

4x = 44

Divide both sides by 4

4x ÷ 4 = 44 ÷ 4

x = 11

step-by-step explanation:

i think you should think about the question and not look online.

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
