First move the terms to get
6m-m=13+2
Then collect the like terms and calculate the sum, 5m=15
Divide both sides by 5
And you get m=3
50 + .35x = 75 + .25x
.1x = 25
25 divided by .1 is 250
going back and checking my work:
50 + .35 (250) = 137.5
75 + .25(250) = 137.5
So the answer is 250 miles
Area of the figure shaded in yellow = 2 x 3 + 2 x 6 = 18 cm²
Total Surface Area = 18 + 18 + (4 + 3 + 2 + 3 + 2 + 6) x 3 = 96 cm²
Answer: 96 cm²
