Find the value of x for which WXYZ must be a parallelogram.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
