Answer:

x = -4 and x = 5

Step-by-step explanation:

Since x^2 + 2x and 3x + 20 both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

x^2 + 2x = 3x + 20

Now we solve the equation.

x^2 + 2x = 3x + 20

x^2 - x = 20

x^2 - x - 20 = 0

(x + 4) (x - 5) = 0

x + 4 = 0 ; x -5 = 0

x = -4 ; x = 5

Solve -7(s+2)-12=37<br> What is s
Shkiper50 [21]

Answer:

<em>s= </em>-5.57 (rounded to the nearest hundredth)

Step-by-step explanation:

1. Multiply s and 2 by 7.

You'll get -7s-14. We'll come back to this later

2. Subtract 12 from 37.

You'll get 25

3. Add 14 to both sides so that you cancel out the -14.

The equation stands as -7s= 39

4. Divide both sides by -7 so that we leave <em>s </em>by itself.

s= -5.57142857

Write a real-world example for -0.2 &lt; -0.1 Please help!
Colt1911 [192]

Answer:

Money

Step-by-step explanation:

This is really dumb, but a person can be in debt by 20 cents and another person by 10 cent; therefore, the person who is in debt by 10 cent obviously has to pay less than the person with the 20-cent in debt. Given these facts, the person in debt with one cent has more money then the person in debt with 20 cents.
