Hello,

Answer:

x = 13

Step-by-step explanation:

7x + 5 + 5x + 19 = 180

⇔ 12x + 24 = 180

⇔ 12x = 180 - 24

⇔ 12x = 156

⇔ x = 156/12

⇔ x = 13

12. An equation is shown. 8 1/2 - 3 1/? = 5 3/12<br>What is the value of the missing number?

weeeeeb [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

$8\frac{1}{2}-3\frac{1}{?}=5\frac{3}{12}$

These are mixed number given.

Suppose the complete mixed number of second place is x.

Converting mixed numbers into fractions.

$\frac{17}{2}-x=\frac{63}{12}$

Adding x in both sides

$\frac{17}{2}=x+\frac{63}{12}$

$x=\frac{17}{2}-\frac{63}{12}$

Making common denominator

$x=\frac{102}{12}-\frac{63}{12}$

$x=\frac{39}{12}$

$x=\frac{13}{4}$

In mixed number form:

$x=3\frac{1}{4}$

So comparing with given equation, the '?' sign will be equal to 4.

Hence the answer is 4 : Answer

Hope it will help :)

Abdul put gas in his car. He paid $18.32 for 8 gallons of gas. What is the unit price?

givi [52]

Answer:

<em>$2.29/gal</em>

Step-by-step explanation:

The unit price is in units of cost per volume, or dollars per gallon, so you divide the cost in dollars by the volume in gallons.

unit rate = ($18.32)/(8 gal) = $2.29/gal
