5/13 is the fraction of cousins that are male.
Answer:
it is no solution i think
Step-by-step explanation:
Let cranberry juice be x.
Let citrus fruit juice be y.
x + y = 630
x + 0.1y = 630*0.23
Solving this yields,
x = 91
y = 539
Therefore, you need 91 oz of pure cranberry juice and 539 oz of fruit juice.
Hope this helps.:)
A direct variation equation always takes the form y=kx, where k is a constant
Let's plug in the values of x=6 and y= -3 to solve for the value of k
-3 = k(6)
Let's flip this equality so we have the k on the left side of the equation.
6k = -3
Let's divide both sides by 6
k = -3/6
Now, simplify the fraction
k = -1/2
Now that we found the value of k, our equation is
y = (-1/2) x
Have an awesome day! :)
