Answer:
y=78
Step-by-step explanation:
y=13(x-4) 2-4
y=(13-52) -2
y=(-24+104)
(2b+-7)+5(b+-3)
Multiply 5 throughout the second parentheses
(2b-7)+(5b-15)
Add 2b and 5b
7b-7-15
Subtract -7 and -15
7b-22
100 divided by 235=0.425
90+0.30m = 70 +0.40m
90-.10m= 70
-0.10m=-20
m=200
more than 200 miles
Part 1: 1 mile.
Part 2: 1.32 mph.
