The percent of discount on the backpack was 42.30%.

Step-by-step explanation:

Step 1:

From the given data, the original cost was $52 and it decreased to $30 due to a discount.

First, we need to determine the difference in values between the original price and the discounted price.

The difference between the prices = 52-30 = 22.

Step 2:  

The percent decrease is given by dividing the difference in values by the original value multiplied by 100.

Percent decrease = \frac{difference in values}{original value}(100) .

Percent decrease = \frac{22}{52} (100) = 0.4230(100) = 42.30 \%

So there was a 42.30% discount on the backpack.

jeka94

Answer:

1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies

2) Now let's consider any real number a no matter positive or negative we will have that:

a-a =0

Or in the other case:

-a -(-a) =-a +a=0

So then we can conclude that the expression is a general rule and is true

Step-by-step explanation:

For this case we can verify if the following expression is true or false:

The sum of x and it’s opposite is always zero?

If we want to proof this we need to show that for any number is true.

1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies

2) Now let's consider any real number a no matter positive or negative we will have that:

a-a =0

Or in the other case:

-a -(-a) =-a +a=0

So then we can conclude that the expression is a general rule and is true
