Answer:
Step-by-step explanation:
"Five times a number" is '5x'.
"Decreased by nine is" '-9'.
"Is equal to" is '='.
"Twice the number" is '2x'.
"Increased by 23" is '+ 23'.
Put them together: 5x-9=2x+23
5x - 9 = 2x + 23 should be the correct answer.

Answer:
B. 4.5 mi.
Step-by-step explanation:
Let g = length of green route
b = length of blue route
(1) 6g + 5b = 52 (2) 12g + 13b = 119
Mult. (1) by -2 <u> -12g - 10b = -104</u>
<u> </u> 3b = 15
b = 5
6g + 5(5) = 52
6g + 25 = 52
6g = 27
g = 27/6 = 9/2
