Answer:
The third one counting from the top.
Step-by-step explanation:
We have the inequality:
(-1/3)*(2x + 1) < 3
The first thing we need to do is isolate x on one side of the inequality.
First we can by -3 in both sides of the inequality, and remember, because we are multiplying by a negative number, the inequality sign changes its direction:
(-3)*(-1/3)*(2x + 1) > 3*(-3)
(2x + 1) > -9
Now we can subtract 1 in both sides:
2*x + 1 - 1 > -9 - 1
2*x > -10
Now we can divide by 2 in both sides:
2*x/2 > -10/2
x > -5
Then we should see a number line such that all the points at the right of -5 are colored.
The correct option is the third one, counting from the top.
Answer:
C
Step-by-step explanation:
The horizontal line, y=2, is solid and shaded above, so it represents

The slanted line, y=x is dashed and shaded below, so it represents y<x.
Answer:
5x + 30
Step-by-step explanation:
5(5+x)
=(5)(6) + (5)(x)
=30 + 5x or 5x + 30

Answer:
1) 25 MPH
2) I don't know. Sorry
3) 25% or 0.25
4) Nope unless you count 1
Step-by-step explanation:
1) 875/25
3) There are 60 animals. Of those 60, 15 are ducks. so, 15/60 = x/100. Cross multiply- 15*100=1500/60=25. To get the decimal, divide by 100.
