He got a 5% raise, so 28,140 is 105% of what it used to be.
105% means 1.05
(1.05) x (salary before increase) = 28,140
Divide each side by 1.05 :
Salary before increase = 28,140 / 1.05 = <u>26,800</u> .
The rest of the question is nonsense. The salary
before increase IS last year's salary.
They are opposites. since |-3| has the lines around it, this represents absolute value, which is not positive or negative but how far away the value is from 0. the plain -3 remains the same. |-3| is 3, because it is 3 units away from 0 on the number line.
Answer:
x = 
Decimal Form: 2.5
Step-by-step explanation:
1) First, you have to simplify 2 − 3x + 3 to −3x + 5.
−x = −3x + 5
2) Next, You add 3x to both sides.
−x + 3x = 5
3) Then, Simplify −x + 3x to 2x.
2x = 5
4) Lastly, you divide both sides by 2 and you're done!
x = 
Decimal Form: 2.5
let's firstly convert the mixed fractions to improper fractions and then sum them up.

Since you want to round to the 10,000 place, you'll want to look at the 2 and the 8 that are next to each other. The 8 makes the two a 3 because it is greater than 5, which gives you 3,430,000. Hope this helped!
