The <em><u>correct answer</u></em> is:

22.5° F.

Explanation:

The temperature increases 1.5° per hour.  From 5:00 AM to 12:00 PM is 12-5 = 7 hours.  This makes an increase of 1.5(7) = 10.5°.

The temperature started at 12°F; increasing by 10.5° gives us

12+10.5 = 22.5°F.

3x - 5 = 10 x = ______
Sphinxa [80]

Answer:

3x - 5 = 10 x

The answer is: x=-\frac{5}{7}

Step-by-step explanation:

3x - 5 = 10x

First, Please, Add 5 to both sides, Which would be:

3x - 5 + 5 = 10x + 5

Second, Please, Simplify your answer, Which would be:

3x = 10x + 5

Third, Please, Subtract 10x from both sides, Which would be:

3x - 5 = 10x = 10x + 5 - 10x

Forth, Please, Simplify your answer, Which would be:

-7x = 5

Fifth, Please, Divide both sides by -7, Which would be:

\frac{-7x}{-7}=\frac{5}{-7}

Last and Finally, Simplify your answer, Which would be:

x=-\frac{5}{7}

I hope I helped :)
