Answer:
n= 3
Step-by-step explanation:
3 (4 + n) = n + 18
you take 3x4=12
then 3x3=9 then you add 12 and 9 which would be in the ( )
12+9 = 21
then if you replace n =3 on other side and add it to 18 answer is 21
therefore both sides would equal 21 so n=3
3(4+3)=3+18
21=21
Answer:
Step-by-step explanation:
1) One solution is to write, as our exponent:
2) Because this is special case of the Exponents Law, valid for every base ≠ 0.
3) Hence, including an exponent the numbers 6, 2 whose value is eight.
Therefore our expression is true
1.
8x = 16
X= 2
2.
=0

Answer:
$59.27
Step-by-step explanation:
It is exponential decrease.
After each year goes by its worth 100 - 0.13 = 0.87 of the previous value.
The equation of decrease is V = 90(0.87)^t where t = the number of years.
So after 3 years it is worth 90(0.87)^3
= $59.27.
