Step-by-step explanation:
Let x be the number of hours for the experienced crew to paint the apartment.
Given:
Experienced crew rate =
New crew rate =
Combined rate =
Solution:
Both crews can paint the apartment in 6 hours. So, painting rate of the both crews is written as:

x = 9 hours.
Therefore, the experienced crew would paint the apartment in 9 hours.
Answer:
i’m pretty sure it’s D
Step-by-step explanation:
multiplying square roots is kind of like multiplying regular whole numbers
6 times 14 equals 84
Just convert the pounds to US dollars and add a 15 increase to that. I got 68.99 pounds.
Based on these first few terms, we can deduce that the next term is computed by switching the sign of the previous one, and multiplying it by 3: we start with -1, we switch the sign (1) and multiply by 3 (3); then again we switch the sign (-3) and multiply by 3 (-9), and so on.
Since switching sign is the same as multiplying by -1, we can compute every next term by multiplying the previous one by -3:
So, the recursive formula is
because it states precisely that the next term is -3 times the previous one.
