Identify the variation as direct, inverse, joint or combined. i = 2pr

Here i is directly related to the joint of p and r, and 2 is a constant . SO in this case , correct option is joint.

If it was i =2p or i = 2r, then it is direct and if it was i=2/p or i=2/r, then it is inverse.

But here it is i=2pr, that is i varies with the joint of p and r, so correct option is joint .

step-by-step explanation:

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":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
