TRANSFORMING FORMULAS Lesson 7-7

Math Vocabulary formula A math statement, usually an equation, that is represented by variables and is used to solve for a specific answer

Transforming Formulas Solve the area formula A = lw for l A = lw *Goal is to ISOLATE the identified variable A = lw w A = l w

Transforming Formulas Solve the perimeter formula P = 2l + 2w for l P = 2l + 2w -2w - 2w P – 2w = 2l 2 2 P – 2w = l 2

Transforming Formulas Solve the variable indicated in red: h = k. j 5a + 7 = b 3 r – 7 = p 4

Practice Solve the variable indicated in red: a) p = s – c b) I = prt c) y = x d) P = 2l + 2w
