Answer:
9) C. 35 + 0.12x = 44.36
10) B
11) A. 32
Step-by-step explanation:
9)
44.36 is the TOTAL so the equations have to EQUAL it.
PER mile means it's a variable so it's 0.12x:
35 is a constant so there's no variable attached:
35 + 0.12x = 44.36
10)
B because you have to cancel the y values and to do that, you multiply the 1st equation by 3.
11)
0.1x + 0.25(46 - x) = 6.70
0.1x + 11.5 - 0.25x = 6.7
-0.15x = 6.7 - 11.5
-0.15x = -4.8
x = 32
 
        
             
        
        
        
Answer:
33.51 cm
Step-by-step explanation:
240/360 = 2/3 (Arc length is 2/3 of the total circumference) 
C = 2 r             ( Calculate the total circumference)
r             ( Calculate the total circumference)     
C = 2(8)
C = 50.265
2/3(50.265)      (Take 2/3 of the circumference. times 2 divide by 3) 
33.51 
Use a calculator and leave the answer to C and then multiply and divide. You get a more precise answer. 
 
        
             
        
        
        
Answer: 
Alonzo was billed for 111 minutes.
Step-by-step explanation:
In this situation, lets let x = minutes. 
0.08x+6=14.88
Subtract the 6 from both sides of the equation.
0.08=8.88
x=8.88÷0.08=111
