Answer:
v = -3
Step-by-step explanation:
-8(v + 7) = 3v - 23
Expand.
-8v - 56 = 3v - 23
Add -3v and 56 on both sides.
-8v - 56 + 56 - 3v = 3v - 23 + 56 - 3v
-8v - 3v = -23 + 56
Combine like terms.
-11v = 33
Divide -11 into both sides.
-11v/-11 = 33/-11
v = -3

Answer:
B
Step-by-step explanation:
$40 is the flat fee of hooking a vehicle. It does not depend on m, miles towed.
$1.70 depends on miles towed, m. So if m miles are towed, the towing fee would be 1.70 * m, or 1.70m.
THAT, would be added to the initial fixed me of $40.
Hence, total charges, c, would be 40 + 1.70m
Answer choice B is right.

Answer:
8 people
Step-by-step explanation:
If 20 of 140 people play tennis, then in a group of 504 people, we expect ...
(20/140) × 504 = 72 . . . . tennis players
If 1 of 9 tennis players has a coach, then in a group of 72 tennis players, we expect ...
(1/9) × 72 = 8 . . . . have a coach
We expect 8 of the 504 people have a tennis coach. We made this prediction by applying the given rates to the larger group.
