4 days • 2 miles = 8 miles
4 days • 3 miles = 12 miles
8 miles + 12 miles = 20 miles in total for all 8 days
Answer: 3p+5=11
Step-by-step explanation:
3p+5=11
-5 -5
3p=6
3p/3=6/3
P=2

40 mph would be 120 miles in 3 hours (120/40)
80 mph is 120 miles in 1.5 hours(120/80)
3 - 1.5 = 1.5, not 3 hrs
Change the speed to 20 mph( 1/2 the speed) to double the hours.
20 mph = 6 hours(120/20)
40 mph = 3 hrs(120/40)
6 - 3 = 3 hours difference
Answer:
Step-by-step explanation:
Perpendicular lines are lines whose slopes are negative reciprocals of each other
To find the slope of the line we are given, we can rearrange the equation

The slope of this line is
, so the slope of the other line is 
next, we can use the given point to find the equation 
we know m, we can solve for b
