Answer: 48
Step-by-step explanation:
To find yy when xx is 12, we can use the concept of direct proportion.
In direct proportion, as one variable increases, the other variable also increases by the same factor. In this case, if xx and yy are in direct proportion, we can set up a proportion using the given information.
Given:
yy = 12 when xx = 3
Let's set up the proportion:
xx / yy = 3 / 12
To find yy when xx is 12, we can cross-multiply and solve for yy:
xx * 12 = yy * 3
12 * 12 = yy * 3
144 = yy * 3
Now, divide both sides of the equation by 3 to isolate yy:
yy = 144 / 3
yy = 48
Therefore, when xx is 12, yy will be 48.
