Answer:
c= 25+0.07 x
Step-by-step explanation:
number of miles travel is represented by "x"
cost per mile is represented by "c"
therefore we have equation,
For 1 mile that is x= 1, cost c= $25.07
For 220 miles that is x= 220
c= 25 + 0.07 * 220
c=25+15.4
c= $40.4
For 220 miles the cost will be $40.4
I think it is C. 14
r+3+4r-28=45
5r-25=45
5r=70
r=14
Answer
The answer is D. 3x+(-2)=2x+4
y=MX+c
2y=3x-7
y=3/2x-7/2
so slope is.. m=3/2
