Answer:
-4(y - 2) = 12
Standard form:
−4y − 4 = 0
Factorization:
−4(y + 1) = 0
Solutions:
y = −4
4
= −1
Step-by-step explanation:
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...
Answer:
7/10
Step-by-step explanation:
To find how many of x are y, you solve <em>y/x</em>.
With our numbers, we have <em>7/6 ÷ 5/3</em>.
We can turn that into <em>7/6 × 3/5</em> = <em>21/30</em> = 7/10.
