Answer:
10 ^(R-15)/3 -2= a
Step-by-step explanation:
R = 3 log (a+2) +15
Subtract 15 from each side
R-15 = 3 log (a+2) +15-15
R-15 = 3 log (a+2)
Divide each side by 3
(R-15)/3 = 3/3 log (a+2)
(R-15)/3 = log (a+2)
The opposite of log is to raise each side to the power of 10
10 ^(R-15)/3 = 10 ^ log (a+2)
10 ^(R-15)/3 = (a+2)
Subtract 2 from each side
10 ^(R-15)/3 -2= (a+2-2)
10 ^(R-15)/3 -2= a
Answer:
13.33333%
Step-by-step explanation:
If we want what percent 5 feet is of37.5 feet, we take 5 feet/37.5 feet to get .1333333 feet.
Then take .1333333 and multiply it by 100 to get 13.33333%
We can test that by doing 13.33333% of 37.5 (or .1333333 x 37.5) and we get 5 feet.
Hope that helps.

Step-by-step explanation:
Answer:
there is a 23% decrease in the price of the house
Step-by-step explanation:
percentage decrease of the price of the house = (price decrease of the house / initial price of the house) x 100
price decrease of the house =new price - initial price
$115,500 - $150,000 = $-34,500
( $-34,500 / $150,000) x 100 = -23%
