Answer:
2 3/4z +3/10
Step-by-step explanation:
3/4(z+ 2/5)+2z
Distribute the 3/4
3/4z + 3/4*2/5 +2z
3/4z + 6/20 +2z
3/4z +3/10 +2z
Combine like terms
2 3/4z +3/10

Answer:
8 cars and 7 vans
Step-by-step explanation:
Let c =number of cars
v = number of vans
c+v = 15
4c+6v = 74
Multiply the first equation by -4 to eliminate c
-4c -4v = -60
Adding the second equation
-4c -4v = -60
4c+6v = 74
-------------------
2v = 14
Divide by 2
2v/2 = 14/2
v = 7
There are 7 vans
c+v = 15
c+7 = 15
c = 15-7
c = 8
There are 8 cars
