3×(60+7)
(3×30) + (3×7)
90 + 21 = 111
Answer:
1/3
Step-by-step explanation:
Range=x maximum (xm) –x minimum (x0)
xm=20+20=40
Coefficient of Range= xm–x0/xm+x0
=40-20/40+20
=20/60
=2/6
=1/3
Answer:
-4/5
Step-by-step explanation:
It is often easiest to count grid squares. But first, you need to find points where the line passes through the intersection of grid lines.
We believe two of those points to be (-3, 1) and (2, -3).
The y-coordinates of these points are 4 units apart, with the point on the right being lower. That is, the "rise" is -4.
The x-coordinates of these points are 5 units apart. That is, the "run" is 5.
The slope is the "rise" divided by the "run":
rise/run = -4/5 = slope
