6 is the answer. 3(6-14)/-4 = 3(-8)/-4 = 3(-2) = -6.
Hope this helps, and have a great day!
Answer:
w=4
Step-by-step explanation:
-80/-5=4
"One rotation" would be the circumference of the wheel, which is
C = 2*pi*r, or (here) C = 2*pi*(8 inches) = 16*pi inches.
1 ft
Convert this to feet: 16*pi inches times ---------------
12 inches
Here "inches" cancels out and you are left with (4/3)pi ft.
So, one rotation of the wheel moves you and your bike forward (4/3)pi ft.
Divide this into 700 feet:
700 ft 2100
------------- = --------- rotations = 525 rotations (answer)
(4/3) pi ft 4
70
make 30 minutes into an hour then divide 140 by 2
140/2=70
70x1=70
