We would convert the gallons to cup hence 1 gallon is equal to 16 cups = gallons
Answer:
I think this is the answer you are looking for. (See below)
Step-by-step explanation:
From the given graph it is noticed that the line is passing through many points.
The coordinates of three given points are (1,5), (-1,-1), (-1,-7)
If a line passing through two points (x1 ,y1) and (x2, y2) , the slope of the lie is defined by, m= y2 - y1/x2 - x1
The line passing through two points (-1,1) and (1,5). So the slope of the line is, m= 5 - 1 / 1 minus -1
m=4/2
Therefore, the slope of the line is 2.

Answer:
8x + 60
Step-by-step explanation:
4(x + 5) + 2(x - 10) + 2(x + 30)
= 4x + 20 + 2x - 20 + 2x + 60 (combine like terms)
= 8x + 60
Answer:
Step-by-step explanation:
<u>The filling speed is 30 hours or:</u>
<u>The draining speed is 34 hours or: </u>
<u>If both lines are open simultaneously, the filling speed is:</u>
- 1/30 - 1/34 =
- 17/510 - 15/ 510 =
- 2/510 =
- 1/255 in an hour
<u>If the tank is 1/5 full, then we need to fill the 4/5 of level and it will take:</u>
- 4/5 : 1/255 =
- 4/5 *255 =
- 204 hours
Here we go ~
[ add 2 on both sides ]
[ form identity : a² + b² + 2ab ]
[ a² + b² + 2ab = (a + b)² ]
so, the value of required expression is 6
[usually positive value is considered, but if asked the value can be either positive or negative]
