Given:
Number of white roses = 4
Number of red roses = 8
To find:
The ratio of the number of red roses to the number of white roses.
Solution:
Using the given information, the ratio of the number of red roses to the number of white roses is
Therefore, the required ratio is 2:1.
Y = kx is the direct variation formula. They are giving y = 48n AFTER they have plugged in a value for x. The value plugged in for x is 16n. To find 'k' we must divide 48n by 16n.
48n/16n = 3 So k = 3.
The equation is therefore y = 3x
Add the 2 1/2 to the other side to get rid of to isolate the x
-27/4= 1/2x divide by 1/2
-27/2=x
The square root of 16 is 4
