Answer:
Step-by-step explanation:
-5(2x - 5) = 8 + (5 - 2x)
-10x + 25 = 8 + 3x
-10x - 3x = 8 - 25
-13x = -17
<u>x</u><u> </u><u>=</u><u> </u><u>1</u><u>7</u><u>/</u><u>1</u><u>3</u><u> </u><u>=</u><u> </u><u>1</u><u> </u><u>4</u><u>/</u><u>1</u><u>3</u>
(7 inches) / 2 = 3.5 inches
Each segment is 3.5 inches.
Answer:
Eastbound train: 95 miles per hour
Westbound train: 105 miles per hour
Step-by-step explanation:
Let:
- e = speed of the eastbound train
- w = speed of the westbound train
The eastbound train travels 10 miles per hour slower than the westbound train
So e = w - 10
Every hour, the distance between the two trains is the sum of the values.
(w - 10) + w = distance apart in 1 hour
5(w - 10 + w) = distance after 5 hours
Solve:
- 5(w - 10 + w) = 1000
- 5(2w - 10) = 1000
- 10w - 50 = 1000
- 10w = 1050
- w = 105
The westbound train is 105 miles/ hour.
The eastbound train is 95 miles per hour
