Answer:
1. 11
2. -82
3. 
4. 36
5. 1
Step-by-step explanation:
1. 3x + 5, when x = 2
Plug in the value of x
3(2) + 5 = 6 + 5
= 11
2. 5xy + x - 4, when x = -3 and y = 5
Plug in the values
5(-3)(5) + (-3) - 4
-75 - 3 - 4 = -82
3. 
, when a = 5, b = 3, and c = 10
Plug in the values
4. 3(xy + 6), when x = -6 and y = - 1
3(-6*-1 + 6)
3(6 + 6)
3(12)
36
5. 
, when x = -3 and y = -8
For the first part, the possible numbers are anything from 20 to 99. That means that there are 79 possible choices that are greater than 19. Sorry I can't help you with the second part.
This depends on whatever the speed the car is going.
