Answer:
Part A: 12.5 cm
Part B: 0.8 km
Step-by-step explanation:
Map scale problems can be solved with proportions.
Part A
5 cm / 2 km = x cm / 5 km
5/2 = x/5
2x = 25
x = 12.5
Answer: 12.5 cm
Part B
5 cm / 2 km = 2 cm / x km
5/2 = 2/x
5x = 4
x = 4/5
x = 0.8
Answer: 0.8 km
Answer: 12
<u>Step-by-step explanation:</u>
The LCM of 48 and 28 is 336
It would take 336 ÷ 28 = 12 revolutions of gear B
and 336 ÷ 48 = 7 revolutions of gear A
to match up the arrows.

Answer:
y = 3x + 19
Step-by-step explanation:
1) Compute the slope (Slope =
)
m = 
2) Refine
m = 3
3) Plug the slope (3) into y = mx + b
y = 3x + b
4) Plug in (-8,-5), x = -8, y = -5
-5 = 3(-8) + b
5) Isolate b
b = 19
6) Construct the line equation y = mx + b
y = 3x + 19
