Answer:
Step-by-step explanation:
the system of equations is:
First, we multiply the second equation by -9:
and now we add this to the first original equation:
we have eliminated the y variable, so we can solve for x:
with this value of x, we substitute it on the second of the original set of equations to find the value of y:
the answer as an ordered pair is:
A - Point Source
This is the answer as a point source is defined as pollution that could come out of varying things which includes a pipe - thus what is depicted within the image. A point source is also pollution which you can detect the source from - non-point source being the opposite.
Hope this helps!
The third is the correct answer because when you reduced 25/65 you will get 5/13
Answer:
Triangular pyramids find the volume by using the equation V=(1/3)AH
Where A = area of base (hint: cut in half and treat like a right triangle knowing the hypotenuse and 1 side)
And H = height

Answer:
$64
Step-by-step explanation:
Given that :
Required amount of olive oil = 2 gallons
Cost per quartz = $8
Recall:
1 quartz = 0.25 gallons
Amount of quartz in 2 gallons :
2 / 0.25 = 8 quartz
Cost of olive oil needed :
8 quartz * $8
= $64
