There were red the red Checkers and black checkers on the checkerboard they were a more red Checkers in a black checkers altogether there between Checkers how many sectors were right and how many checkers are black

There are 14 red checkers and 6 black checkers on the checker board.

Step-by-step explanation:

Given:

Total number of checkers in all = 20

We need to find the number of checkers red and number of checkers black.

Solution:

Let the number of black checkers be 'x'.

Now given:

There are 8 more red checkers than black checkers

Number of red checkers =

Now we can say that;

Total number of checkers in all is equal to sum of number of black checkers and Number of red checkers.

framing in equation form we get;

Subtracting both side by 8 we get;

Dividing both side by 2 we get;

Number of black checkers = 6

Number of red checkers =

Hence There are 14 red checkers and 6 black checkers on the checker board.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
