Answer:
The sale is 5% off.
Step-by-step explanation:
- $25 regular price.
- $18.75 sale price.
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, <em>5</em><em>%</em><em> </em><em>of </em><em>2</em><em>5</em><em> </em><em>=</em><em> </em><em>?</em>
5% * 25 = 1.25
You needed $1.25, 5% gives you that.
Therefore, the answer is 5%.
The sum of x and 9 divided by 2 is equal to 3x
(x + 9)/2 = 3x
Note the equal sign, what you do to one side, you do to the other. First, multiply 2 to both sides
(x + 9)/2(2) = 3x(2)
x + 9 = 6x
Subtract x from both sides
x (-x) + 9 = 6x(-x)
9 = 5x
Isolate the x. Divide 5 from both sides
9/5 = 5x/5
x = 9/5
9/5 is your answer for x
hope this helps
