8is 40% of what number? show your work

Do a proportion
40/100= 8/x
8 x 100= 800
Cross multiply and divide
800 divided by 40= 20
So answer is 20

8 = 40%

Divide each side by 2.

4 = 20%

Multiply each side by 5.

4*5 = 20

20*5 = 100

8 is 40% of 20.

Check:

20 * 0.4 = 8

The correct answer is: b

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
