A line is 180 degrees. Right? Okay.
Although there is a line between them, both angles will sum up to 180 degrees.
So the equation will be: 3x-20+x=180
You need to isolate the variable.
First add like terms: 3x+x=4x
So then the equation is 4x-20=180
After that you add 20 to both sides because the opposite of -20 is +20, and Denver what you do on one side needs to be reappeared to the other side
4x-20=180
+20 +20
4x= 200
Dived both by 4
4x=200
/4. /4
X=50

Angles:
X=50
3(50)-20=130(angle)

A leaky pool loses 2 1/4 inches of water eachday. Jermain and mildred are asking to determine the change in the amount of water

Answer:

Over 5 days, the pool loses 11 $\frac{1}{4}$ inches of water.

Step-by-step explanation:

Since the leaky pool is losing water at a rate of 2 $\frac{1}{4}$ inches of water each day, than we can find the amount of water the pool has lost over 5 days, by either adding 2 $\frac{1}{4}$ five times, or just multiplying 2 $\frac{1}{4}$ by 5:

2 $\frac{1}{4}$ x $\frac{5}{1} =\frac{9}{4} x\frac{5}{1} =\frac{45}{4} =11\frac{1}{4}$
