Rearrange linear formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm's law V = IR to highlight resistance R.
Clarifications, limits, emphases, and other information intended to ensure appropriate variety in tasks:
1. Tasks have a real-world context.
2. The quantity of interest is linear in nature.
Sample Questions (taken from PARCC’s Practice Tests and Released Items):
PBA Released Test Item 6
Practice Test, Unit 2, Item 5 (Paper Test, Unit 2, Item 18)

1. PBA Released Test Item 6

A set production designer creates a right circular cylindrical pillar. The designer knows the amount of material used for the surface of the pillar and needs to find the height for a reinforcement rod.

Use A = (2𝝿r)h + 𝝿r2, where r represents the radius, h represents the height of the pillar, and A represents the surface area of the pillar. What is the formula for h in terms of the other variables that can be used to find the height?

a. h = A-𝝿r2
b. h = A + 𝝿r2
c. h =      A   
d. h =      A     _   1
              3𝝿r        2

2. Paper Test, Unit 2, Item 18
The formula for finding the perimeter, P, of a rectangle with length l and width w is given.    P = 2l + 2w
Which formula shows how the length of a rectangle can be determined from the perimeter and the width?

a. l = P - 2w
b. l = P - 2w 
c. l =  P + w
d. l = P - 2
