Answer:
40 ft/in
Step-by-step explanation:
There is 40 feet for every inch of the model
26 = 5 (x + 10) + 3x
26 = 5x + 50 + 15x
26 = 5x +15x + 50
26 = 20x + 50
26 - 50 = 20x - 50
-14 = 20x
-14 / 20 = x
-0.7 = x
5/7m - 2 - 6/7m = -13
5/7m - 6/7m - 2 = -13
-1/7m - 2 = -13
-1/7m = -11
-m/7 = -11
-m = -77
m = 77
