Solve for x: -0.25(-x-12)=2​

Mathematics
1 answer:
AlladinOne [14]3 years ago
5 0
Expand the brackets by multiplying everything in the brackets by -0.25.

-x x -0.25 = 0.25x
-12 x -0.25 = 3

0.25x + 3 = 2

-3 from both sides.

0.25x = -1

Divide both by 0.25

x = -4

Two chemical plants are releasing waste into a holding tank. Plant 1 releases waste twice as fast as plant 2. Together they fill
tatiyna

Answer:

6 hours.

Step-by-step explanation:

Let t represent time taken by plant 1 in hours to release the waste.

Part of waste released by plant 1 in one hour would be \frac{1}{t}.  

We have been given that two chemical plant 1 releases waste twice as fast as plant 2, so time taken by plant 2 to release the waste would be 2t.

Part of waste released by plant 2 in one hour would be \frac{1}{2t}.  

We are also told that together they fill the tank in 4 hours. So part of tank filled by both plants working together in one hour would be \frac{1}{4}.

\frac{1}{t}+\frac{1}{2t}=\frac{1}{4}

\frac{1}{t}\cdot 4t+\frac{1}{2t}\cdot 4t=\frac{1}{4}\cdot 4t

4+2=t

t=6

Therefore, it will take 6 hours for the faster plant to fill the tank working alone.

So you do 100-3.4 = 96.6, the divide by 100 = 0.966
Then you do 0.966^3 x £6000 = £5408.6
