Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
5x < 20
Step 2: Solve for <em>x</em>
- Divide both sides by 5: x < 4
Here we see that any number less than 4 will work. So numbers like 3, 0, or even -12587235897 would work.
Answer:
The mass is greater by 10.502 grams. If you subtract 27.33 from 16.718, you get 10.502. Therefore, the mass of the second coin is greater than the first coin by 10.502 grams.
Step-by-step explanation:
Add 1 to both sides
Multiply both sides by 4
Take the square root of both sides
Subtract 5 from both sides

Answer: C
Step-by-step explanation:
(fog)(3) is the same as finding f(g(3)). To solve, we first need to solve g(3). then, we solve for f(g(3)).
g(3)=5(3) [multiply]
g(3)=15
Now, we plug in 15 into f(x).
f(g(3))=-2(15)+8 [multiply]
f(g(3))=-30+8 [add]
f(g(3))=-22
Now, we know that C is the correct answer.
