Question

To cook the meat for the pasta dish takes 2 minutes less than four times the amount of time it takes to boil the noodles. the time to cook the meat is 30 minutes. how long does it take to cook the noodles?

Answer 1

8 minutes

Explanation:

Correct equation: 4n - 2 = 30

Add two to both sides: 4n - 2 + 2 = 30 + 2

Simplify: 4n = 32

Divide by four on both sides: 4n ÷ 4 = 32 ÷ 4

Simplify: n = 8

Answer 2

Answer: 8 minutes.

Explanation:

1. Let's call the time to cook the noodles:
`x`.

2. You must use the following information given in the problem to write an equation:

-The time to cook the meat is 30 minutes.

- The time to to cook the meat takes 2 minutes less than four times the amount of time it takes to boil the noodles.

3. Therefore, you have:

`30=4x-2`

4. Solve for
`x`:

`x=(32)/(4)\\x=8`

5. The answer is: 8 minutes.
