Answer:
50-2.5t=w. no, the water will all have drained by then.
Step-by-step explanation:
2.5 per min so
min=t
therefore 2.5t
theres 50 quarts of water
50-2.5t = w (water left in the tank)
_____________________________________-
part 2,
2.5*30 = 75, and 50<75
this is impossible.
Answer: whats the answer
Step-by-step explanation:
He used 53 pounds. I got this by using two equations.
a+b=117
and
5.8a+4.1b= 569.8
I took the first equation and subtracted 'b' so the equation looked like a=117-b.
I then plugged in 117-b into the second equation, so it ended up looking like this:
5.8 (117-b)=569.8
5.8 times 117 is 678.6. And 5.8 times negative b is negative 5.8b.
The equation now looks like this:
678.6-5.8b+4.1b=569.8
Add like terms
678.6-1.7b=569.8
Then subtract 678.6 from both sides
-1.7b= -108.8
divide each side by -1.7
you get b= 64.
But because you are looking for how many pounds for a, subtract 64 from 117. You get 53. 53 is the answer.
