Order of Operations is a very important math concept to understand. Order of Operations is a set of math rules that tell you which math operations like addition or multiplication to do first. If you always follow the rules that go along with Order of Operations, you will always get the same answer. They are 4 rules.

First: Parentheses and Brackets

Next: Exponents

Then: Multiplication and Division

Last: Addition and Subtraction

Dafna1 [17]
<h2>log (6 ) + log ( 8 ) − log ( 2 ) </h2><h2 /><h2>  Answer:</h2>

Exact Form:    ㏒ ( 24 )

Decimal Form:    1.38021124


<h2>Explanation:</h2><h3>                            Use the product property of logarithms,  </h3>

                                ㏒b ( x)  +  ㏒b ( y )  =  ㏒b ( x y ).

                                 ㏒ ( 6 ⋅ 8 ) −  ㏒ ( 2 ) .


<h3>                         ⇒Use the quotient property of logarithms,</h3>

                                 ㏒ b ( x ) − ㏒ b ( y ) = ㏒ b ( x y ) .

                                 ㏒ ( 6 ⋅ 8/ 2 )

<h3>                          ⇒Reduce the expression by cancelling the common factors. </h3>

                                Factor  2  out of  6 ⋅8 .

                                log ( 2 ( 3 ⋅ 8 )  / 2 )

<h3>                             Divide  3 ⋅ 8   by  1 .</h3>

                                ㏒ ( 3 ⋅ 8 )

                                Multiply  3  by  8 .

                                 ㏒ ( 24 )

<h3>The result can be shown in both exact and decimal forms. </h3><h3>                            Exact Form:  ㏒ ( 24 ) </h3><h3>                            Decimal Form:  1.38021124</h3>

Darcy, Jason, and Maria share 268 dollars. Jason has 20 dollars more than Darcy and Maria has twice as much as Jason. How much m
frosja888 [35]

Answer:

The amount of money that Darcy and Jason have together is $124

Step-by-step explanation:

Let

x -----> amount of money that Darcy has

y -----> amount of money that Jason has

z ----> amount of money that Maria has

we know that

x+y+z=268 ------> equation A

y=x+20 -----> x=y-20 -----> equation B

z=2y -----> equation C

substitute equation B and equation C in equation A and solve for y

(y-20)+y+2y=268

4y-20=268

4y=268+20

4y=288

y=72

Find the value of x

x=y-20 -----> x=72-20=52

so

The amount of money that Darcy has is $52

The amount of money that Jason has is $72

therefore

$52+$72=$124

The amount of money that Darcy and Jason have together is $124

weeeeeb [17]

Let there be a advanced tickets and s same day tickets, Then:-

a + s = 40

20a + 30s = 950............................(1)

Multiply first equation by -30

-30a - 30x = -1200 .....................(2)

Adding equations (1) and (2):-

-10a = - 250

a = -250/-10 = 25

So s = 40 - 25 = 15

Answer:-  advanced tickets cost $25 and same day cost $15.

Thank you for posting your question here at brainly. Below ist he answers:

a. T= d/r
b.  It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something. 
c. T= d/r
T= 32.12 m /<span>8.8 m/min
T= 3.65 min
