I'm so confused. Please help I tried the first time got 50 some thing then 33 then 20.25. How do I do this?

vazorg [7]

Answer:

Basically, you have to think: more bricks : more time

more workers : less time

2,400 bricks 6 workers takes 18 hours

You now have to solve for 4,500 blocks and 10 workers

4,500 / 2,400 = 1.875 (times greater)

10 / 6 = 1.666666666 (times less)

So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666

which equals 20.25 hours

So, it seems you were correct on your third try.

Solve Ax+Hy=K for x<br> Help!

denis23 [38]

Answer:

$x = -\frac{Hy + K}{A}$

Step-by-step explanation:

Step 1: Add -Hy to both sides.

$Ax + Hy - Hy = K - Hy$
$Ax = -Hy + K$

Step 2: Divide both sides by A.

$\frac{Ax}{A} = \frac{-Hy+K}{A}$
$x = -\frac{Hy+K}{A}$
