Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>
  • \sqrt{ \frac{x}{y} }  <  =  >  \frac{ \sqrt{x} }{ \sqrt{y} }  \\ and \:  \\  \sqrt{x}  \times  \sqrt{y}  =  \sqrt{xy}
  • PEMDAS

let's solve:

a) \sqrt{ \frac{9}{25} }

\frac{ \sqrt{9} }{ \sqrt{25} }

\frac{3}{5}

b) \frac{ \sqrt{12} }{ \sqrt{3} }

\frac{ \sqrt{12} }{ \sqrt{3} }  \times  \frac{ \sqrt{3} }{ \sqrt{3} }

\frac{ \sqrt{12 \times 3} }{ (\sqrt{3} )^{2} }

\frac{ \sqrt{36} }{3}

\frac{6}{3}

2

c) \frac{ \sqrt{15} }{ \sqrt{3} }

\sqrt{5}

What value of x makes the equation true?<br><br> 16 + (18 + 10) = (x + 18) + 10<br><br> x = ?
choli [55]

Answer:

  See below

Step-by-step explanation:

16 + (18 + 10) = (x + 18) + 10x

16 + 28 = (x + 18) + 10x        Add like terms in the parentheses

44 = (x + 10x) + 18               Use the community property to regroup like

                                            terms

44 = 11x + 18                         Simply

<u>-18 =        -18</u>                         Substract 18 from both side

26  = 11x                               Simply

<u>26</u>  =  <u>11x</u>                              Divide by 11

11        11

2\frac{4}{11} = x                               Reduce

Kaitlyn tony and juan served a total of 71 orders Monday at the school cafeteria. Toney served 9 fewer orders than kaitlin. Juan
morpeh [17]

Answer:

<u>Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Total of orders server at the school cafeteria by Kaitlin, Tony and Juan = 71

Tony served 9 orders fewer than Kaitlin

Juan served 2 times as many orders as Kaitlin

2. How many orders did each one serve?

For answering this question, we should prepare and write down our equation this way:

x = Number of orders served by Kaitlin

2x = Number of order served by Juan ( 2 times as many orders as Kaitlin)

x - 9 = Number of order served by Tony (9 orders fewer than Kaitlin)

x + 2x + x - 9 = 71

4x = 71 + 9

4x = 80

x = 80/4 = 20

x = 20 ⇒ 2x = 40 ⇒ x - 9 = 11

<u>Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.</u>
