Sally plans to run 12 miles. She ran 5 1/8 miles and then stopped for a water break. How many miles does Sakky have left to run?

1 answer:

3 0

So,

We can just subtract the fractions without converting any denominators. To do that, we can split the subtraction problem up as follows:

12 - 5 - 1/8
7 - 1/8
6 7/8

Sally still has 6 7/8 or 6.875 miles to run.

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

Use the mirror equation:

1/di + 1/do = 1/f

where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)

Substitute and solve for do.

1/do + 1/(-10 cm) = 1/(15 cm)

1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)

do = 6 cm

Hope it helps you
