Answer:
A: 336 km
B: 14 L
Step-by-step explanation:
Use a proportion
210 km / 5 L = x / 8L Cross multiply
8*210 = 5 x
1680 = 5x
x = 1680 / 5
x = 336 km
===============
210 /5 = 588/x Cross multiply
210x = 588 * 5
210x = 2940 Divide by 210
x = 2940/210
x = 14 L

Answer:
-2.5
Step-by-step explanation:
We need to find the slope using and two points
m = ( y2 -y2)/(x2-x1)
= ( 25-20)/(-10 - -8)
= 5/( -10+8)
= 5/-2
- 2.5
