Answer:
4
Step-by-step explanation:
You need to try out all the numbers.
lets start with 4
if there where 4 red marbles then there would be 9 times as many marbles
so 4 x 9 = 36
Now we add and see if the sum is 40
36 + 4 = 40
We got it on the first try
You can use the same method on more problems like these.
Hope this helps :)
Given:
A line AB joins the points A (3,4) and B (5,8).
To find:
The midpoint of the line AB.
Solution:
Midpoint formula:
A line AB joins the points A (3,4) and B (5,8). So, the midpoint of line AB is
Therefore, the midpoint of the line AB is (4,6).
The answer is G. Perpendicular lines have opposite reciprocal slopes
