A slice of pizza costs $1.57. How much will 27 slices cost?
elena-s [515]

It will be cost $ 42.39 for 27 slices of pizza

<h3>Further Explanation</h3>

A slice of pizza = $1.57

27 slices of pizza = the number of pizza x price/slice

                              = 27 x 1.57

We are going to use standard algorithm to solve this multiplication

  1.57        ⇒ 2 decimal places

<u>     27</u>    x   ⇒ 0 decimal place

 1099

<u> 314   </u>+

42.39        ⇒ 2 decimal places

In decimal number multiplication, the process is the same with the whole number multiplication. Only always remember when to put the decimal point in the answer.

Solve for x: 9(x+1) = 25+X
Inessa [10]

Answer:

x=2

Step-by-step explanation:

9(x+1) = 25+x

<u />

  9x+9=25+x      

   

<u>Subtract x on both sides:</u>

  8x+9=25                      

   

<u>Subtract 9 on both sides:</u>

<u />

        8x=16    

                           

<u>Divide both sides by 8:</u>

          x=2
