  1. Algebra 1: Section 2-6 Formulas

  2. OBJECTIVES: • To transform literal equations

  3. A Literal Equation is... • An equation involving two or more variables. • Example: Formulas such as • P= 2L + 2W • A= LW • A = ½ h(b1 + b2) • A = ½ bh

  4. Examples: • Solve for w. • P=2(l +w) • P = 2l+2w • -2l -2l • P-2l = 2w • 2 2 • P-2l = w • 2 • Solve for x. • Y – 4 = 3x – 8 • +8 +8 • Y – 4 = 3x • 3 3 • Y – 4 = x • 3

  5. Example: • Solve for p. • M – hp = d • -M -M • -hp = d – M • -h -h • P = d – m • -h

  6. Example: • You can use the number of chirps n a cricket makes in one minute to estimate the outside temperature F in degrees Fahrenheit. Transform the formula F=n/4 +37 to find the number of chirps in terms of temperature. How many chirps per minute can you can expect if the temperature is 60 degrees F.

  7. Check For Understanding: • Solve for h. • V = lwh • Solve for t. • A = P + Prt

  8. Assignment: • Pg. 113: multiples of 3 #3-39, 26, 41, 44, 45, 46, 49
