Answer:
is there supposed to be a picture with it? i can't solve it without more information. sorry
For there to be an infinite number of solutions, the quantity on the left side of the equation must be the same as on the right.
First, distribute the equation to get
6x + 18 = 3xh + 9h
If h = 2, the equation on the right would also be 6x + 18 which would yield the same equation and hence an infinite number of solutions
So the answer is h = 2
As Mifc8 said, one can easily do 1.7*1080=1836 feet.
1.)9a+4c=43
2.)4 adults and 4 children
3.)27$
4.)y=.10+40
5.)y=.20x+18
That's all I have so far
(I think 6.) is 193 but I'm not positive)
