Answer:
Step-by-step explanation:
-8-4v=40 add 8 to both sides
-4v=32 divide both sides by -4
v= -8
3v+2v=25
5v=25 divide both sides by 5
v=5
x/2 - 8 = -14 add 8 to both sides
x/2= - 6
-6 * 2= -12
check
-12/2-8=-14
-6-8=-14
-14= -14
-6+n/3= -3 add 6 to both sides
n/3=3
3*3=9
check
-6+9= -3
-3 = -3
Answer: 
Step-by-step explanation:
You can use the following formula:

You can say that "T" is the time (in minutes) for both faucets working together, "A" is the time (in minutes) for cold water faucet working alone and "B" is the time (in minutes) for hot water faucet working alone.
Based on the data given in the exercise, you can identify that:

Therefore, substituting these values into the formula and solving for "B", you get that this is:
