I need to know how to solve 7/20=

1 answer:

6 0

First off, you can use your calculator.

7 / 20 = 7 divided by 20

You can multiply both top and bottom by 5.

This is to make the bottom 100.

(7*5) / (20*5)

35 / 100

0.35

7/20 = 0.35

Answer:

Option C) supplementary

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

In this problem

The measure of angles are

60° and 120°

Their sum is equal to

60° + 120°=180°

therefore

The two angles are supplementary

Answer:

150 miles

Step-by-step explanation:

let m represent miles

$70 + .70m = $40 + .90m

subtract 40 from each side

$30 + .70m = .90m

subtract .70m from each side

$30 = .20m

divide both sides by .20

150 = m
