Answer:
Step-by-step explanation:
-12 = 3/4n + 8....subtract 8 from both sides
-12 - 8 = 3/4n
-20 = 3/4n.....multiply both sides by 4/3, cancelling the 3/4 on the right
-20 (4/3) = n
-80/3 = n
ur answer is A
Answer:

Step-by-step explanation:
Answer:
0.4077
Step-by-step explanation:
It's important to use parenthesis to avoid confusion.
9^(2x) = 6
Use exponent properties:
(9^2)^x = 6
81^x = 6
Take log of both sides
ln(81^x) = ln(6)
Use log properties:
x ln(81) = ln(6)
Solve for x:
x = ln(6) / ln(81)
x ≈ 0.4077
Answer:
Step-by-step explanation:
the number is 1300 if we have 40% from it will give us 520
The Jasmine result is the good one because 1 mégas meter=1 000 000
