Answer:
Elena could tell without finishing by simplifying both sides. The next step would have been 30x +24x = 30x+24. This would have been simplified down to x=1

Answer:
Step-by-step explanation:
Part A : when comparing graphs : A system of equations will have no solutions (on a graph) when your lines never cross each other. They never cross each other because your lines are parallel.
Part B : by comparing each algebraic equation : A system of equations will have no solution if your lines are parallel. Parallel lines will have the same slope but different y intercepts. Example :
2x - y = 2
4x - 2y = 8
put both equations in slope intercept form
y = 2x - 2
y = 2x - 4
they both have the same slope of 2.....and the y intercepts are different....meaning they are parallel lines and have no solutions
First, we need to figure out the volume of the cylinder that holds the ink. The formula for the volume of a cylinder is

We have the diameter, but we can easily find the radius by dividing it by 2. 0.400/2=0.200. Now, we plug our numbers into the formula.

Now, we need to figure out how much ink he uses each week. We do this by dividing the volume by the amount of weeks, or 1.445/7 = 0.206.
So, the student uses

ink each week.
Answer:
Area is 1000π
Step-by-step explanation:
@Texaschic101 you are correct .75 x 64 will indeed equal 48 sq feet. so your answer will be 64 tiles. hope this was of help!
