1. Rearranging Formulas Lesson 5

2. Things to Remember If adding or subtracting, use the zero effect to isolate the variable. If there is only one fraction, use the zero effect first then multiply by the denominator. If there is more than one fraction, use the LCM first, then zero effect if needed.

3. Solve the formula for w A = lw Things to Remember: Isolate the variable You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate = AlAl A = lw lw l AlAl =w

4. Solve the formula for h A = Things to Remember: Isolate the variable You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate = A = bh = 1212 bh 1212 2(A) 2 () 1212 bh bh2A 2A b = bh b 2A b = h

5. Solve the formula for a g = a + w Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate g = a + w g - w = a + w - w g - w = a

6. Solve the formula for t W = R + Ht Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate W = R + Ht W - R = R - R + Ht W - R = Ht W - R H = Ht H W - R H =t

7. Solve the formula for u v = u + at Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate

8. Solve the formula for u v = u + at Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate v = u + at v = u + at v - at = u + at - at v - at = u

9. Solve the formula for R C = F + Rn Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate

10. Solve the formula for R C = F + Rn Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate C = F + Rn C = F + Rn C - F = F - F + Rn C - F = Rn C - F n = Rn n C - F n = R

11. Solve the formula for u s = ut + at 2 Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate 1212

12. Solve the formula for u s = ut + at 2 Things to Remember: Isolate the variable Use the zero effect You may need to multiply by the variable in the denominator You may need to divide by the variable in front of the variable you want to isolate s = ut + at 2 s = ut + at 2 2(s) = 2(ut) + 2( at 2 ) 2s = 2ut + at 2 = 2s - at 2 2t =u 1212 1212 1212 2s - at 2 = 2ut + at 2 - at 2 2s - at 2 = 2ut 2ut 2t = stst - at 2
