Answer:

12n-10=14, n=2

Step-by-step explanation:

( Twelve times of a number decreased by 10 is equal to 14 ) This sentence can be written mathematically to be: 12n-10=14

The answer: Add 10 to both sides: 12n-10=14 > 12n-10+10=14+10 > 12n=24

Divide both sides by 12: 12n=24 > $\frac{12n}{12} =\frac{24}{12}$ > n=2

How do I find miles per hour when I get minutes and miles

Scilla [17]

In this case you have:

$\frac{miles}{minute}$

An hour has sixty minutes.

$\frac{60 minutes}{1 hour}$

<span>You must multiply by this equality.

</span> $(\frac{miles}{minute})(\frac{60 minutes}{1 hour})=\frac{(miles)(60 minutes)}{ (minute)(hour)}=\frac{(miles)(60)}{(hour)}$

<span>You must multiply by 60 and you can convert miles per minute to miles per hour.</span>
