In 4 hours if you count the miles by the road linking the 2 buses. This is because 55 for one bus and 45 for the other bus added together equals 100 miles/hour. Therefore, 4 hours will be the time the 2 buses are 400 miles apart.

Schach [20]
Currently the car is worth $12,780. This is 72% of the original price. Therefore, we get the following:

72 % = $12,780
1 % = 12,780 / 72
100% = 12780 / 72 * 100 = $17,750

Consider this equation: 9x - 7 - 3x + 9 = x + 7 + 5x + 9. How many solutions does this equation have?
garri49 [273]

Final Answer: No Solution. The equation would have 0 solutions.

Steps/Explanations:

Hey there! The answer is No Solution because -7 = 7. If 7 = 7, then it would be true and have one solution, which is not the case here.

<u>Step 1</u>: You should cancel 9 on both sides.

9x - 7 - 3x = x + 7 + 5x

<u>Step 2</u>: Simplify 9x - 7 - 3x to 6x - 7.

6x - 7 = x + 7 + 5x

<u>Step 3</u>: Simplify x + 7 + 5x to 6x + 7.

6x - 7 = 6x + 7

<u>Step 4</u>: You'll need to cancel 6x on both sides.

- 7 = 7

<u>Step 5</u>: Since -7 = 7 is false, there would be no solution.

No Solution
