Answer:
E = 8
Step-by-step explanation:
y - x = 4
y - (3y) = 4
y - 3y = 4
2y = 4
y = 4/2
y = 2
x = 3y
x = 3×2
x = 6
x + y = 2+6
x+y = 8
The K-team can paint a whole house in 60 minutes (super fast!!!). How much of a house can the team paint in 1 minute? The K-team can paint 1/60 of a house per minute.
The C-team can paint a whole hose in 80 minutes. How much of a house can the team paint in 1 minute? The C-team can paint 1/80 of a house per minute.
Suppose both teams paint for the same amount of time -- call the time t (minutes).
Combine the work they do to paint 1 whole house:

Multiply all the terms by the Least Common Denominator, LCD = 240.

Now, can you finish it? By the way, the answer is not a whole number! Hint: it will be between 30 and 40 minutes.
Answer:
x=2
Step-by-step explanation:
5x+10=24-2x
5x+10-10=24-2x-10
5x= -2x+14
5x+2x= -2x+14+2x
7x=14
7x/7=14/7
x=2
They’re equal. 8 is 2/3 of 12.
