Answer:
1020 = 6*(x+17)
x = 153
Step-by-step explanation:
1020 = 6*(x+17)
1020 - total
6 - number of tickets
x - one ticket price
17 - insurance
1020 = 6x + 102
1020 - 102 = 6x
918 = 6x
x = 918/6
x = 153
400+8x=800-6x.
Solving for x, you get 14x=400, and x is around 28.57
So it takes around 28.57 minutes for them to have the same amount of water.
Answer:
(x+1) is a factor with remainder 0.
Step-by-step explanation:
We divide (x+1) into the polynomial 
through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial .
We subtract this from the original 
.
This leaves 
. We repeat the step above.

We subtract this from 
. There is no remainder. This means (x+1) is a factor.
Answer:
first blank: three dimensional
second blank: object
third blank: cuts
Step-by-step explanation:
A cross section is the intersection of a three-dimensional figure and a plane.
A cross section is the shape we get when cutting straight through an object.
Different cross sections can be taken of the same solid. A plane can slice through a solid in any direction. The resulting figure of a cross section depends on how the solid is "sliced".
