Step-by-step explanation:
3(2 + 3 + 4)^2
3(9)^2 = 3(81) = 243
For this case, the first thing we must do is define variables.
We have then:
x: amount of time the assistant works
Y: amount of time the experienced person works
We then have the following system of equations:
x + y = 4
y = (1/2) x
Solving the system we have:
x = 8/3
y = 4/3
Answer:
It would take the roofer, working alone, to complete the same job about:
y = 4/3 hours
La repuesta es “x = 7”.
9x + 8 = 11x - 6
-9x -9x

8 = 2x - 6
