What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as D

Now , the value of D is

Substituting the values in the equation , we get

Let the total distance ran by Johnny be D = ran 2 miles north, 6 miles west, 3 miles north, 10 miles south, 8 miles east, and then 2 miles

So , D = 2 + 6 + 3 + 10 + 8 + 2

On simplifying the equation , we get

D = 31 miles

Hence , the distance is D = 31 miles

The answer is r=-9

Answer: 4.5

Step-by-step explains:  1) 2r - 9 = -18

                                          2r - 9 + 9 = -18 + 9

                     2)  ( 9 + 9 )      Add the numbers

                       ( -18 + 9 )    add the numbers

                                            2r = -9

What value of x makes the equation below true? −2x=−36 A x=−34 B x=−38 C x=−18 D x=18

Answers

Answer:

D x = 18

Step-by-step explanation:

Given equation:

−2x = −36

Divide both sides by -2 to find x

−2x / -2 = −36 / -2

x = −36 / -2

x = 18

x = 18 makes the equation −2x = −36 true

Suppose y is directly proportional to x. If y= 24 when x=2, what is the value of x when y= 144?

Answers

Answer:

12

Step-by-step explanation:

Because y=24 and x=2 you do the following:

144/24=6

Then, 6x2=12 because it is proportional

Or you could do 24/2=12 and 144/12=12

Answers

The value that Mrs. Alvarez will pay depends on the rental value of the ski and the poles per day, for example $144.

How to calculate the total loan cost of Ski equipment?

To know the total cost of the loan of the Ski equipment, we must know the loan price per day or per hour.

For example, suppose the loan price per hour is $2, then we would have to calculate how much one day is equivalent to and then multiply it by the total number of days.

$2 x 24 = $48

$48 x 3 = $144

Was it just because my parents were arguing again and I needed to get out? What the heck.. of course its because of the bet and maybe because I wanted to get away from my parents. She is not fun and super rude. Id never want to hang out with her on my own. This is definitely for the bet. All that laughter and fun was totally fake. Shes still an annoying spoiled brat.. right? I really dont know how to see her anymore because right now she looks really adorable feeding the ducks. She has a big smile on her face and she generally looks really happy. Happy suits her.

I smile and do as she says. My name is Seth. You can stop calling me pretty boy. She looks at me with a grin and says, You know, I think I like pretty boy better. She laughs and I glare at her. Thats what I said to her earlier when Ava told me her name. Well, I guess I am pretty. I say in a confident tone. She looks at me and responds, Not even close. I glare at her some more. Shes definitely still mean and bratty. Aww, did I make you mad? She asks in a mocking tone. Of course she did but Im not admitting that to her. I walk towards her and she stops laughing and asks, What are you doing? I grin at her secretly knowing that shes going to hate me even more after I do this. I walk even closer and push her into the pond. She screams and she hits the water and is completely soaked. Oh my gosh! What is wrong with you?! I hate you! She screams at me but Im too busy laughing to pay attention. The next thing I know, Im in the pond too. She grabbed my leg and pulled me in. I should have seen that coming. Now shes dying of laughter. I cant believe you just did that! I say to her. She starts laughing again and through her laughter says, Oh come on! You totally deserved that! I smile and say, I guess I did. She giggles. That annoyingly adorable laugh she has is driving me crazy. We should go, its getting late. I say to her. Yeah, probably. She replies.
