Answer:
I believe the answer is x< -141/7
−141
7
Step-by-step explanation:
Step 1: Subtract 15 from both sides.
−35x+15−15>720−15
−35x>705
Step 2: Divide both sides by -35.
−35x/-35> 705/-35
x < -141/7
Hope this helps! :)
Answer: B

Substituting into y=3x+b,

Answer:
18.5
Step-by-step explanation:
120.25/6.5
M represents miles
35+0.10m=25+0.15m
35-25+0.10m=25-25+0.15m
10+0.10m=0.15m
10+0.10m-0.10m=0.15m-0.10m
10=0.05m
m=200
Check:
35+0.10(200)=25+0.15(200)
35+20=25+30
55=55
The solution: m=200 is true.
After 200 miles driven, prices charged by both companies will be the same.
D.-15x+30/7
-5(3x-6/7)=-15x+30/7
