Answer:
6 minutes
Step-by-step explanation:
Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.
If they work together, they will be checking at a combined rate of:
1/10 + 1/15 = [3(1) + 2(1)]/30
= 5/30 = 1/6
Their combined rate is 1/6 which means they check one set in 6 minutes
Answer: The minimum is 16, probably arranged in 4 rows of 4 buttons.
Step-by-step explanation: just grab a calculator lol
Right side:
(1/27)^(2x+10)
=(3^-3)^(2x+10)
= 3^(-6x - 30)
Re-write both sides:
3^(4x-5) = 3^(-6x - 30)
from here, you can solve x
4x - 5 = -6x - 30
4x + 6x = -30 + 5
10x = -25
x = -2.5
Answer:

Step-by-step explanation:
To solve this problem is multiply 2 by 2 and then 2 which gives you 8.
Then you will add 2+2+2 and get six. For when multiply exponents you are adding.
