Step-by-step explanation:
Here is the workings
2x+4y+6+2y-5+3x combine like terms
2x+3x+4y+2y+6-5
Step 2
2x+3x+4y+2y+6-5 Add the similar exponents
5x+4y+2y+6-5
5x+6y+6-5
Step 3
5x+6y+6-5 Add and subtract
Your answer would be 5x+6y+1
It will take 16hr 30min for Mrs. Smith to catch up.
<h3>
To find how many hours will it take Mrs smith to catch up:</h3>
Let,
t + 3 = Time of Mr. Smith
t = Time of Mrs. Smith
v1 = 55 mph the speed of Mr. Smith
v2 = 65 mph the speed of Mrs. Smith
Formula: Distance = speed × time
v1 ( t + 3) = v2t
55 ( t + 3 ) = 65t
65t = 55t + 165
65t - 55t = 165
10t = 165
t = 16.5 hr
t = 16 hr 0.5 × 60 min
t = 16 hr 30 min
Therefore, it will take 16hr 30min for Mrs. Smith to catch up.

Answer: S = 8
Step-by-step explanation:
If the bus begins its route with no passengers, that is P = 0
P = –2(S – 4)2 + 32 = 0
(- 2S + 8)4 = - 32
-8S + 32 = - 32
-8S = - 64
S = 64/8 = 8
The value of S when the bus has its greatest number of passengers?
