Pretty sure it’s 65 since its alternate interior angles which equal 180
        
             
        
        
        
Answer 6 hours
Reason
7x + 9.50 = 55
 -9.50. -9.50 subtract from both sides
_____________
7x = 45.50
Divide both sides by 7 to isolate x
X = 6.5
So he can rent for 6 hours (the .5 would be charged as a full hour per the problem)
        
             
        
        
        
Answer:
<h3>             FALSE</h3>
Step-by-step explanation:
The  statement "The expression contains 2 terms." is false because the expression contains 3 terms:  7f, 15 and -2g
 
        
             
        
        
        
10) (9,-3); m=2
(a) y=2x-11
Plug in the variables that are constant on both the given line and the new one.
y=mx+b
-3=2(9)+b
Do not input b, as the y intercept is relative to the specific line, and not others. 
-3=18+b
-3-18=b
-21=b
The y intercept of the new line is -21. 
FINAL ANSWER::y=2x-21
(b) y=2x-21
Plug in the variables that are constant on both the given line and the new one.
y=mx+b
-3=2(9)+b
Do not input b, as the y intercept is relative to the specific line, and not others. 
-3=18+b
-3-18=b
-21=b
The y intercept of the new line is -21
FINAL ANSWER::y=2x-21
Or equivalent to the original. 
Hope this helps you solve the rest. ;)
