10^2 is 10×10 which is 100
4^2 is 4×4 which is 16
so it simplifies to 100-16×2. By Order Of Operations, parentheses, exponents, multiply and divide, add and subtract 100-16×2 makes 100-32 which is 68

Two trains leave Cleveland at the same time. One train travels east and the other travels west. The speed of the westbound train

OlgaM077 [116]

Answer:

The eastbound train travels at 92 mph and the westbound train travels at 96 mph.

Step-by-step explanation:

We know that Velocity = distance / time

If the eastbound train travels at x miles per hour, the westbound train travels at x + 4 mph.

After 3.5 hours, they are 658 miles apart. If we solve for distance the formula given above we have: Distance = velocity x time. We have that the total distance between both trains is 658 miles.

Substituting the values of the problem and solving for x we have

$658 = 3.5x+3.5(x+4)\\658=3.5x+3.5x+14\\644=7x\\92=x$

Thus, the eastbound train travels at 92 mph and the westbound train travels at 96 mph.
