5^(x+3)=25^(x-2)

Apply the exponent rule ( 5 ^2 = 25, so remove the 5 and replace 25?with 2)

x + 3 = 2(x-2)

Simplify:

X + 3 = 2x -4

Add 4 to both sides:

X + 7 = 2x

Subtract x from both sides

X = 7

Answer: x = 7

Your fuel expense for last year was $800 this year it was $960 what was the percentage of increase. A.23% B.18% C. 15% D.20%

Answer:

The percentage of increase in fuel expenses is 20%

Step-by-step explanation:

Given:

Fuel expense in last year = $800

Fuel expense in this year = $960

To Find:

The percentage of increase

Solution:

Let the percentage increase be X

Then X = $\frac{\text{final value}-\text{starting value}}{\text{starting value}}\times 100$

Now substituting the values we get,

$X =\frac{960-800}{800}\times 100$

$X =\frac{160{800}\times 100$

$X =0.2 \times 100$

X= 20%
