Answer:
Hence, 3/2 and 1 are the roots of the equation.
6-4(2/3)
5(3/3)-4(2/3)
1(1/3)
Let's look at work rates per minute.
Together they can paint the wall in x minutes.
Working together, in 1 minute, they do 1/x of the job.
The student who paints the wall in 16 minutes does 1/16 of the job in 1 minute.
The student who paints the wall in 24 minutes does 1/24 of the job in 1 minute.
Together, they do 1/16 + 1/24 of the job in 1 minute, but from above, we see that together, they do 1/x of the job in 1 minute, so 1/16 + 1/24 must equal 1/x. That gives us our equation.
1/16 + 1/24 = 1/x
1/16 * 3/3 + 1/24 * 2/2 = 1/x
3/48 + 2/48 = 1/x
5/48 = 1/x
x = 48/5 = 9.6
Answer: It takes them 9.6 minutes, or about 10 minutes to do the job together.
Answer:
1: 3/4
2: 1080
Step-by-step explanation:
I hope this is right and helps you out!
Treat each side as if it's their own equation.
14-2*2
First multiply
14-4
Now subtract
10/5
Now divide
2
2 is the answer
