Question

literal equations - worksheet #2

1. solve for b: a = \frac{1}{2}bh (area of a triangle)
2. solve for r: c = 2\pi r (circumference of a circle)
3. solve for w: p = 2l + 2w (perimeter of a rectangle)
4. solve for t: d = rt (linear motion)
5. solve for c: f = \frac{9}{5}c + 32 (temperature conversions)

Explanation:

5)

Step1: Multiply both sides by 2

$2A = bh$

Step2: Divide both sides by h

$b=\frac{2A}{h}$

Step1: Divide both sides by $2\pi$

$r = \frac{C}{2\pi}$

Step1: Subtract 2L from both sides

$P - 2L=2W$

Step2: Divide both sides by 2

$W=\frac{P - 2L}{2}$

Answer:

$b=\frac{2A}{h}$
