25 x² - 10 x = 0
5 x ( 5 x - 2 ) = 0
x = 0  and
5 x - 2 = 0
5 x = 2
x = 2: 5 
x = 2/5

Answer:

B. x = 0 and x = 2/5

Step-by-step explanation:

To get the value satisfying the equation, we will need to simplify the given equation 25x²-10x = 0 to have:

First we will factor out '5x' which a common factor to have;

5x(5x - 2) = 0

5x = 0 and 5x-2 = 0

From 5x = 0, x =0

From equation 5x-2=0, 5x= 0+2

5x = 2

Dividing both sides by 5 which is the coefficient of x we have;

5x/5 = 2/5

x = 2/5

The solutions will give;

x = 0 and x = 2/5

Helen got a 7% reduction in the price of pair jeans that are normally $32. What is the approximate percent decrease in the price
Colt1911 [192]

A percentage is a way to describe a part of a whole. The approximate percent decrease in the price is 21.87%, thus, the correct option is B.

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given the reduction in the price is $7, while the original cost is $32. Therefore, the approximate percent decrease in the price is,

Percentage decrease = 7/32  × 100%

                                     = 21.87%

Hence, the approximate percent decrease in the price is 21.87%, thus, the correct option is B.

The correct question is:

Helen got a $7 reduction in the price of a pair of jeans that are normally $32. What is the approximate percent decrease in the price?

The percent decrease is approximately 15%.

The percent decrease is approximately 21%.

The percent decrease is approximately 43%.

The percent decrease is approximately 78%
