Question

Ok I know it’s late but I really need help with these problems and no one can help me so can someone please help and explain. I know it’s a lot but I’m really confused, thank you so much.

Answer 1

1. x = 0.75

2. p = 4

3. L = 11

4. t = 42

Explanation:

1. The price of pen is x, then

=> 6x + 24 = 28.5

=> 6x = 4.5

x = 4.5/6 = 0.75

2. p is the number of lbs

=> 2p + 50 = 58

2p = 8

p = 4

3. Perimeter = 2(L + W)

2(L + 4) = 30

=> 2L + 8 = 30

2L = 22

L = 11

4. t is the number of tickets

3t + 24 = 150

3t = 126

t = 126/3 = 42
