A sporting goods store displays the following sale sign. What percent off is the sale advertising?
Regular Price
(dollars)
25
Sale Price
(dollars)
18.75

The sale is 5% off.

Step-by-step explanation:

You need to find the percentage that deducts $1.25 from the regular price. I start with 5% and work my way up from there until I find the answer.

So, 5% of 25 = ?

5% * 25 = 1.25

You needed $1.25, 5% gives you that.

Therefore, the answer is 5%.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
