Solving Scale Measurements and Angle Equations - DPP-19 Activities
This document outlines the DPP-19 activities from January 17 to January 20, 2012. The tasks include calculating the real engine length based on a model scale of 1:72 for a 6-inch model, solving basic algebraic equations involving variables, and finding complementary and supplementary angles. Each day's work has specific assignments and due dates, including turning in previous assignments. The document emphasizes practical applications of math concepts, including geometry and algebra.

DPP-19 Tue, Jan 17, 2012. • If a train model has a scale of 1:72, how long is a real engine for a 6 inch long model. Give your answer in inches and feet. Turn in DPP-18today.
DPP-19 Wed, Jan 18, 2012. • −13 −15 = • −13 + 15 = • −13 − (−15) = Turn in ICE-13 today.
DPP-19 Thu, Jan 19 Solve the following equations. • 7x + 13 = 2x + 28 • 3(x + 7) = 12 N-14 is due today.
DPP-19 Fri, Jan 20 • If the measure of an angle is 75o, what is the measure of its complementary angle? • If the measure of an angle is 165o, what is the measure of its supplementary angle? Turn in DPP-19 & HW 7-1 today.
