Answer:
B=55
Step-by-step explanation:
2x+3x+2x+5=180
7x=175
X=25
B= 2x+5
B=2*25 +5
B=55
The fixed amount is 6 because it's 6 dollars for 0 miles traveled.
Y=-4
This line also is equals Zero, if that makes any sense lol but y= -4 is the correct equation.
Adding them up, we have 1/2+3/20+2/5+4/5. We can do a bit of guess and checking to see that 2, 5, and 20 go into 20. 20/2=10 and 20/5=4, so we multiply 1/2 by 10/10 and 2/5 and 4/5 by 4/4 to get 10/20+3/20+8/20+16/20= 37/20
