Answer:

The question has a mistake

Step-by-step explanation:

11d+7c= 172.5

10d+7c= 155.8

By subtraction;

1d+ 0c = 16.7

1d = 16.7

11×16.7+7c=172.5

7c = 172.5-11*16.7

You will get a negative answer yet the cost cannot be negative.

The function rule T(m)=450-8m represents the amount of water T(m) (in liters) in a holding tank after being drained at a rate of
suter [353]
Well they give you the equation and they want you to solve for time given that you know the amount of water in the tank.  They tell you T=274 and that

T=450-8m  so using the value T=274 in the equation to the left gives you:

274=450-8m  subtract 450 from both sides

-176=-8m  divide both sides by -8

22=m

So 22 minutes have passed when there is 274L remaining...

VARVARA [1.3K]
If 1/6 of the pan was left and there were 2 pieces left you just need to set 1/6 equal to 2/some number, this allows you to say that 1/6=2/x --> x/6=2-->x=12. My explanation might be a little poor since this becomes fairly fundamental later on but hopefully it helps.
