The equation y=-0.04x + 12 gives the number of
gallions of gas in your car, where x is the number of
miles driven

Given: △abc, ab=15, bd=9 ad ⊥ bc , m∠c=30°. find: the perimeter of the triangle.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
