- Mordancy
You need to set both of them equal to zero to find what w is. so its 3w-5=0 you add 5 to get w by itself so then its 3w=5 and then divide by 3 so w= 5/3
1 + w = 0 so then you subtract one to get to the other side so w = -1
the final solution is {5/3, -1}
Answer:
Jim's hose: 27 hours.
Bob's hose: 21.6 hours.
Step-by-step explanation:
Let t represent hours taken by Jim's hose.
Part of pool filled by Jim's hose in 1 hour would be 
.
We have been given that Bob's hose, used alone, takes 20% less time than Jim's hose alone. This means that Bob's hose take will take 80% time of Jim's hose that is 
.
Part of pool filled by Bob's hose in 1 hour would be 
.
We are also told that it takes 12 hours using both hoses. Part of pool filled by both hoses in 1 hour would be 
.
Now, we will add rates of both hoses and equate with as:
Cross multiply:
Therefore, it will take 27 hours for Jim's hose to fill the pool alone.
Time take by Jim's hose alone: 
.
Therefore, it will take 21.6 hours for Bob's hose to fill the pool alone.

Question
An expression can often be used to model a real-life situation. For each of the following expressions, write a real-life situation using money as the context. Then, evaluate the expression and interpret the result in terms of the situation. Here's an example.
The following situation is modeled by the expression -24.50 + 100.00: Jonathan overdrew his checking account by $24.50. He then transferred $100.00 from his savings account to his checking account. His new checking account total is $75.50.
Make sure to use complete sentences in your answers.
1) $8.15 + $11.99
2) $20 - $18.04
3) 7($1.45)
4) 42.08 / 4
It's too short. Write at least 20 characters to explain it well.
Angle 1=x
Angle 2=y
x+y=180(linear pair)
y=180-x___(1)
(3/2)x=y
(one angle is 1and half the measure of the other)
3x=2y
substitude (1)
3x=2(180-x)
3x=(360-2x)
5x=360
x=72degree
y=180-x
y=108degree
