3.4 hours. The efficiency of a worker is the amount of work divided by time needed. The efficiency of Sanjay alone is 500/6, and the efficiency of Felipe alone is 500/8. When they work together, their combined efficiency is 500/6+500/8=3500/24. Therefore, they need 500/(3500/24)=24/7=3.4 hours.
Hey there!
2(6 * 4) + 2(6 * 2.4n) + 2(4 * 2.4n)
= 2(24) + 2(14.4n) + 2(9.6n)
= 48 + 28.8n + 19.2n
= 48 + 48n
= 48n + 48
Thus, your answer should be: 48n
Good luck on your assignment and enjoy your day!

Answer: x+3
The original function tells us to subtract 3 from the input x.
The inverse function will do the exact opposite: it adds 3 to the input x.
-18(1) = -18,right?
4(3) = 12, right?
-18 - 12 = -30
From the looks of it, we had to "Subtract" the outcome of each problem that we went over
You're correct: -30 (option A.) would be your answer
This is some simple Algebra
So it's 4x+16=-2
We subtract 16 from both sides
4x=-18
Sivide both sides by 4
X=-4.5
If you need more of an explanation I am happy to elaborate
