21 out of 24 students did their homework. what percent did not do their homework.

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

12.5%

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
