Answer:

Step-by-step explanation:
51 / 13 = 3.9231 = 3
51 - (13 x 3) = 12

Answer:
0 => -⅘ => 1.5 => 3 => -4 => 
Step-by-step explanation:
The greater the absolute value of a slope, the steeper the slope. By absolute value, we mean the non-negative value of tthe .
To arrange the slope values, from the least steep to the steepest, ignore the negative sign in any of the slope values.
Thus, in the order from the least steep to the steepest, we have:
0 => -⅘ => 1.5 => 3 => -4 =>
The greater the absolute value of the slope, the greater the vertical movement. The greater the vertical movement, the steeper the slope.
A slope value of 0 connotes a horizontal line.

Step-by-step explanation:
I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the <em>whole</em> trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.
