Zaria wants you to solve this puzzle: “i am thinking of a number. if you divide my number by 2 and subtract 4, you will get 2. what is my number?

Let

x--------> the number

we know that

solve for x

Adds both sides

Multiply by both sides

therefore

the answer is

the number is

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9
