is 7:4 which of
which of the following
could be the total number of
marbles in the box and how

a) 18 (B) 9 (c). 21 (d)22​

Answer 1

Answer:

(d) 22

Step-by-step explanation:

See we have 7x red marbles and 4x blue marbles we want to determine the total number of marbles in the box.

When we multiply 7x and 4x by 1, we get 7x and 4x which gives us the total of 11x. Which is no where near to the answer given in the options.

Now, suppose that x=2

Then we put the values of x in 7x we get 14 and similarly 8x which gives us the total of 22x. So here we get our answer, that our answer could be 22x.

Hope you can understand the answer.
