(3,0) and (0,6)
Y= -2x + 6
0= -2x + 6
-6/-2 = 3
X= 3
(3,0)
Y = -2(0) + 6
Y=6
(0,6)
The large hose fills 1 pool in 9 hours written as 1/9
The small hose fills 1 pool in 18 hours, written as 1/18
Now you have 1/9 + 1/18 = 1/x ( x is the unknown time for both hoses).
rewrite 1/9 with a common denominator as 1/18:
1/9 = 2/18
Now you have 2/18 + 1/18 = 1/x
Add the left side:
2/18 + 1/18 = 3/18
Now you have 3/18 = 1/x
Cross Multiply:
3x = 18
Divide both sides by 3"
x = 18/3
X = 6
It will take both hoses 6 hours.
With what? I don’t see anything
Answer:
139.71
Step-by-step explanation:
22% of 179.11 is 39.40
179.11 - 39.40 = 139.71
X=2
you multiply by 8 on both sides. so that your equation now looks like x-2=0
then you will add by 2 on both sides.
x=2
