Answer:
A)4.1%
Step-by-step explanation:
First you need to add all the payments together to get your total.
1400+300+150+800+300+150+100+100+150+200=3650
Then you cross multiply and divide to get the percentage.

=
When you cross multiply and divide x≈4.1 
 
        
                    
             
        
        
        
Answer:
a. -2
b. s = 2 and y = -5
c. (2.5, -9)
d. -7x - 2
Step-by-step explanation:
a. In the image, I have used rise over run, which is -8/4 or -2.
b. slope formula is mx + b = y, where m is slope and b is the y-intercept. In the equation 2x - 5y = -10, 2 is the slope and -5 is the y-intercept.
c. Plug in all given numbers into an equation and the ones you do not have will be in the points you need it to be. Once you graph the equation you will receive (2.5, -9).
d. y = mx + b
    5 = (-7)(-1) + b
    5 = 7 + b
    -2 = b
y = -7x - 2   
 
        
             
        
        
        
Answer:
x=23.5
Step-by-step explanation:
90=25-x/2+18
combine like terms 
90=43-x/2
subtract 43 from both sides
47= -×/2
47/2= 23.5
x=23.5
or
90-25= 65
65-18=47
47/2=23.5
