A simplified ratio may always be a rate.
Answer:
there would be 160 as if 25% of the student body is 40 then you would multiply it by 4 to get to 100% of the student body thus giving you 160.
Step-by-step explanation:
Slop: second one (2/1)
Y-intercept: first one
Explanation
Slop is rise over run so how much it goes up or down on the top and how much it goes our right on the bottom
Y-intercept is where the point intersects with the y line so what point is on the y line
THIS IS NOT A LINK USE THE DESMOS GRAPHING CALCULATOR
We know the perimeter is the total sum of all sides of the shape, we can use this to form an equation: the perimeter=1st side + 2nd side + 3rd side + 4th side 39a-7=9a+(5a+1)+(17a-6)+4th side.
Collect like terms to get 39a-7=31a-5+4th side
If we move everything but the 4th side over to the left we can solve
C. 8a-2=4th side is the correct answer
