Answer:
-20
Step-by-step explanation:
-8v-9=7
Add 9 to each side
-8v-9+9=7+9
-8v = 16
Divide by -8
-8v /-8 = 16/-8
v = -2
Now find
7v -6
7(-2) -6
-14 -6
-20

Answer:
Step-by-step explanation:
57 lb bag for $ 11 or 1 lb bag for $ 0.41
11/51 = 0.215 .....rounds to 0.22 ......this is the correct way...... the student messed up and divided wrong.
the large bag only charges $ 0.22 per lb, whereas, the small bag charges $ 0.41 per lb.
So each 1 revolution it travels the distance around the rim of the wheele aka circumference
circumference=pi times diameter
diameter=21
circunference=pi times 21 or 21pi
so distance=number of revolutions times circunference
number of revolutions=3
subsitute
distance=3 times 21pi
distance=63pi
answer is 63pi
or aprox pi to 3.14 and do 63 times 3.14=197.82
aprox 197.82 inches
