Answer: 2 x 3 - 5 x 2 + 25
Step-by-step explanation: Remove the up arrow and put a space after each letter and numbers so it makes more sense.
2x +2(x-12)=340
2x+2x-24 = 340
4x=364
x = 91
91-12 = 79 mph for eastbound train
You could do rise/run
count how many units the line goes up(rise), then how many units the line goes horizontally(run), then divide.
