Since the real track has a gauge of 3 feet but the model railroad track has a gauge of 3/4 inches, the scale factor must be 1/4, because you must follow the rule
"true measurement * scale factor = model measurement"
In fact, we have
This implies that the original driving wheels height, 44 inches, must be scaled down to
inches.
Answer:60.9
Step-by-step explanation:
3 - 14 = 5x + 67 - 5x
11 = 5x + 67 - 5x
11 = 5x + 62x
11 = 67x
11/67
60.9
N= 12
Subtract 70.85 and 7.25 which equals 63.6. Then take 63.6 divided by 5.3 and it equals 12! Hope this helps.
2 3/4 that is at least the shortest term
To determine if it is a solution you have to plug in the given number [a=0] so 0-5 /0+5
-5/5 =-1 not 1.
