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.
For the answer to the question above, asking to g<span>raph the six terms of a finite series where a1 = 5 and r = 1.25.
I'll provide the answer with the solutions below.
</span>a1 = 5
<span>a2 = 5*r = 5*(5/4) = 25/4 </span>
<span>a3 = 5*r² = 5*(5/4)² = 125/16 </span>
<span>a4 = 5*r³ = 5*(5/4)³ = 625/256 </span>
<span>a5 = 5*r⁴ = 5*(5/4)⁴ = 3125/1024
</span>I hope this helps
Answer:
x = 2
Step-by-step explanation:
To find the x-value that makes the equation true, we would have to solve for x in the equation. To do that, we would have to get the equation in the form x = _. That would be our answer.
4x - 3 = -9 + 7x
Add 9 to both sides to get rid of the -9 on the right side.
4x - 3 + 9 = 7x
Simplify.
4x + 6 = 7x
Subtract 4x from both sides to get rid of the 4x on the left side.
6 = 7x - 4x
Simplify.
6 = 3x
3x = 6
Divide both sides by 3 to get rid of the coefficient of 3 on the left side.
x = 6/3
Simplify.
x = 2
So, the x-value that makes the equation true would be 2.
I hope this helps. :)
