Answer:
R=(4,5)
Step-by-step explanation:
M={x1+x2/2,y1+y2/2}
(6,7)={8+x2/2,9+y2/2}
Equating the x coordinates and y coordinates
6=8+x2/2
12=8+x2
x2=12-8=4
7=9+y2/2
14=9+y2
y2=14-9=5
4000
as the first bit rounds to 5 and the second bit rounds to 800
First know how many pounds are in a ton
there are 2000 pounds in a ton
so simply divide
7000/2000=3.5
So there are 3.5 tons of brick on the truck
