5 0

Answer:

Step-by-step explanation:

The 5 parts of the ratio represents 10 boys.

Divide number of boys by 5 to find the value of one part of the ratio.

$\frac{10}{5}$ = 2 ← value of 1 part of the ratio

There are 6 parts of the ratio representing girls, thus

6 × 2 = 12 ← number of girls in the class

Answer:

x = 34

Step-by-step explanation:

The angles x + 12, 100, and x add up to a straight angle, so the sum of their measures is 180°.

(x + 12) + (100) + (x) = 180

x + 12 + 100 + x = 180

2x + 112 = 180

2x = 68

x = 34
