8 is 10% of 80

Convert the percentage into a decimal:
\frac{10}{100} = 0.1

Multiply the decimal by 80:
0.1 \times 80 = 8

Which expressions are equivalent to_____? Check all that apply.
Alinara [238K]

Option 1. (-2)(5x) + (-2)(-\frac{3}{4}) and option 4.-10x + \frac{3}{2} are equivalent to -2(5x-\frac{3}{4} ).

Step-by-step explanation:

Step 1:

The given expression is expanded as follows.

The -2 is multiplied with the 5x and then the -2 is multiplied with the -\frac{3}{4}.

So the expression becomes as follows;

-2(5x-\frac{3}{4} ) = (-2)(5x) + (-2)(-\frac{3}{4}).

This is the first option given so the first expression is equivalent.

Step 2:

-2(5x-\frac{3}{4} ) = (-2)(5x) + (-2)(-\frac{3}{4}) = -10x + \frac{6}{4} = -10x + \frac{3}{2} .

Of the other four options, only the fourth expression has the fraction \frac{3}{2} so the fourth expression is also equivalent.

Expressions 1 and 4 are equivalent to the given expression.

The width of a rectangle is 5 centimeters less than the length. The area is 36 square centimeters. Find the length.
charle [14.2K]
If the width is Wthen the length is 2W-5 W(2W-5)=422W2-5W = 422W2-5W-42 = 0 Factor by grouping or do the quadratic equation.Multiply the coefficient of the squared term.. 2..by the constant ..-42..   2(-42)=-84Factors of -84 that add to the coefficient..-5.. ofthe W term are  7(-12)Replace the -5W with  -12W + 7W 2W2-12W+7W-42 = 02W(W-6) + 7(W-6)=0(2W+7)(W-6)=0
 Either:   2W+7 = 0   or   W-6 = 0             2W = -7           W = 6 cm             W = -7/2 cm

Since W will not be a negative, our width is 6cmThe length is 2W-5 = 2(6)-5=12-5 = 7 cm
