Answer:

x = 12

Step-by-step explanation:

The given angles are supplementary. Therefore, they have a sum of 180°.

8x - 20 + 8x + 8 = 180

16x - 12 = 180

16x = 192

x = 12

Fabio has run five eighths of the race. What fraction of the race remains?
Pavel [41]

Answer:

\frac{3}{8}

Step-by-step explanation:

<h2><u>Fractions </u></h2>

since \frac{5}{8} has been completed

the remaining would be :

\frac{8}{8} -\frac{5}{8}

since <em>denominators are the same </em>

= \frac{8 - 5}{8} \\\\

= \frac{3}{8}

<u>the fraction of the race that is remaining is 3/8</u>

stepan [7]

Answer:

1 and 1/30 gallons

Step-by-step explanation:

First, convert all the fractions to a common denominator. I'm choosing 30.

1/3=10/30  1/5=6/30  1/2=15/30

Now, you can add them together to get 31/30, so a little more than a gallon
