Answer:
x = 27
Step-by-step explanation:
x/3-9=0
Add 9 to each side
x/3-9+9=0+9
x/3 = 9
Multiply each side by 3
x/3*3 = 9*3
3
3.2 hrs
4/5* 4 = 16/5=3.2
B is equal to 10
You can add those two numbers together and set equal to 90. This would allow you to solve for B
B + 3B + 50 = 90
4B + 50 = 90
4B = 40
B = 10
