Question

Algebra: Distributive Property Solve for variables using distributive property and balancing method. A.) 3.5 (4.5p - 6) = 89.25 B.) 2½ (n - 1) + 0.5 (n + 3) = 8

Answer 1

Answer:

A) 3.5 (4.5p - 6) = 89.25

=> 3.5x4.5p - 6x3.5 = 89.25

=> 15.75p = 89.25 + 21

=> p = 110.25/15.75

=> p = 7

B) 2.5(n-1) + 0.5 (n+3) = 8

=> 2.5n - 2.5 +0.5n +1.5 = 8

=> 3n - 1 = 8

=> 3n = 9

=> n = 3
