Mathematics

So when you work with variables (x, y or any other letter), when they're beside a number it usually means to multiply.

So 3y can also be written as 3(3). So 3 multiplied by 3 is equal to 9

So now our problem looks like this,

x/9.

Since we already know what x is equal to, our problem will look like this

18/9.

So now all we have to do is divide.

18 divided by 9 is 2

So therefore, your answer is 2.


I hope this helps :)

-2(x+1)+6x&lt;-14<br>I need help​
jeka57 [31]

Answer:

x<-3

Step-by-step explanation:

-2(x+1)+6x<-14

Distribute

-2x-2 + 6x < -14

Combine like terms

4x -2 < -14

Add 2 to each side

4x-2+2 < -14+2

4x < -12

Divide by 4

4x/4 < -12/4

x<-3

An online video store charges $24 please help
mr Goodwill [35]

Answer:

B. 24d + 4; $76

Step-by-step explanation:

Part 1: If the online store charges $24 per DVD, this is the same as saying "24 multiplied by the number of DVDs bought".

It's given that "d" represents the number of DVDs

  • So the first part of the variable expression is: 24d

If the online store also charges an additional $4 per <em>order,</em> that means that it's only $4 extra for the whole order. NOT per DVD you buy.

  • Result: 24d + 4

Part 2: If someone were to buy 3 DVDs, that would mean that d = 3.

To find the total cost, substitute 3 for d into the expression.

  • 24d + 4
  • 24(3) + 4
  • 72 + 4 = 76
  • Result: $76
