Answer: n = 4
Step-by-step explanation: you combine the like variables which turns it into
(4y - 3)
(4y - 3) is <em>another</em> way of saying ((4 x y) - 3)
So the 4 is turned into n making it (ny - 3)
To find population density, it is population / area.
The population is 6688, divided by the area of 16.
6688/16 = 418
So the population density is 418 people per sq mile.
The answer would be the second one, the graph is decreasing everywhere
15 624/1000 is it supposed to be sipplified?
Answer:
r = -4
Step-by-step explanation:
Step 1: Write out equation
4r + 8 + 5 = -15 - 3r
Step 2: Combine like terms
4r + 13 = -15 - 3r
Step 3: Add 3r to both sides
7r + 13 = -15
Step 4: Subtract 13 on both sides
7r = -28
Step 5: Divide both sides by 7
r = -4
