Answer: a = 15
Step-by-step explanation:
6a + 10 = 3a + 55
Subtract 10 from both sides
6a = 3a + 45
Subtract 3a from both sides
3a = 45
Divide each side by 3
a = 15
Answer:
Step-by-step explanation:
I am assuming the tank starts empty. It means that in 1 hour the tank has half that water, or 3600 gallons. And the good thing of lines passing through 0.0 is that the value at 1 IS the slope we need. ie 3600.
At this point it's easy to find that if in 2 hours it filled 1/10th of the tank, in 20 hours the tank will be full.
Graph done with paint, obviously not to scale.
We need to combine like terms, so 4x-3x, and 8y+2y. x+10y is it simplified
It would take 24 days for the patch to cover half of the lake
The answer is y=-2x+6
We know the slope of the given equation is -2. A parallel line must have the same slope as the original function. So if we plug in the coordinates and the slope into the point slope formula we get y=-2x +6
