SVETLANKA909090 [29]

If 21 out of 24 students did their homework, 3 out of 24 did not do it.

This written as a fraction is 3/24 and can be reduced to 1/8.

This in decimal form is 0.125 .

To convert the decimal to a percent, multiply by 100 and put a percent sign at the end of the number.

0.125 × 100 = 12.5

What is the value of x? Enter your answer in the box
noname [10]

Answer:

x=12

Step-by-step explanation:

First add the two equations: 10x-20+6x+8=16x-12

Since the two angles equal 180, we know the following equation: 16x-12=180

Add 12 to both sides then divide by 16.

x=12

Hope this helps!
