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
2𝝿r
b. h = A + 𝝿r2
2𝝿r
c. h = A
3𝝿r2
d. h = A _ 1
3𝝿r 2
2. Paper Test, Unit 2, Item 18
