The sum of my number and two and two thirds is seven. What is my number? 7 is in one box. Below it are 2 boxes. N is in one. 2 and 2-thirds is in the other.

Check all that apply.
The variable, n, represents the unknown number.
The unknown number and 2Two-thirds equals 7
4 One-third+2Two-thirds= 7
9 Two-thirds- 2Two-thirds= 7
n = 4 One-third

Four times my number is 36. What is my number?

The variable, n, represents  

✔ the unknown number

.

The bar diagram demonstrates that four of the unknown numbers together make  

✔ 36

.

4 ×  

✔ 9

= 36

The number is  

✔ 9

.

Step-by-step explanation:

you have 6 cupcakes

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
