162 degrees

Step-by-step explanation:

First find the fraction of medals that the usa won

total medals: 31+20+6+6+6 =69

fraction = 31/69

A circle has 360 degrees so multiply the fraction by 360 degrees

31/69 * 360

161.7391304

About 162 degrees

161.74

Step-by-step explanation:

if you want to make a circle graph, there are two ways.

1. using degree, 1 full circle is 360°

2. using percentage, 1 full circle is 100%

the to find the degree from data

we just use the ratio.

USA/SUM = x°/360°

31/(31+20+6+6+6) = x/360

31/69 = x/360

(31)(360) : 69 = x

x = 161.74° (if you need the decimal)

x ≈ 162 (rounded)

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
