40% of 20 equals 8.

First, we need to think that 20 is our 100%.
Let's make the variable v as the value we're looking for.

20/v = 100/40
We need to multiply both sides of the equation by v.
(20/v) * v = (100/40) * v

Now, we're left with 20 = 2.5x

We need to divide both sides of the equation to isolate the variable x.
20/2.5 = 2.5x/2.5
8 = x

Our final answer is 8.

PLEASE HELP god bless Justify each step of the solution by stating the property that was used to get to each step. Given: 4(-6x

baherus [9]

4(-6x – 3) + 24x = -72x + 132

Step 1 -24x – 12 + 24x = -72x + 132 Distribute Property of Equality

Step 2: –12 = -72x + 132 equivalent

Step 3: -144 = -72x Subtraction Property of equality

Step 4: 2 = x Equivalent / Division property of equality

For a trapezoid, the following formula relates the area a, the two bases a and b, and the height h. a= g (a

Dovator [93]

A - area of a trapezoid;
a, b - two bases.
A = h * ( a + b ) / 2 / * 2 ( we have to multiply both sides by 2 )
2 A = h *( a + b )
2 A = h a + h b
h b = 2 A - h a
b = ( 2 A - h a ) / h
b = 2 A/h - a
