Linear Equation: 15m+10=w 15 pages written for every month for 5 months plus the 10 pages she has already written is equal to the total number of pages written in 5 months. m= number months written. In this case, it is 5 months. w= number of pages written in 5 months 15(5)+10=w 75+10=w 85 pages written=w Carla will have written 85 pages in 5 months.
You can show the angles at either end of segment BC in triangles MBC and LCB are congruent, so you have two angles and the segment between. The appropriate theorem in such a case is ASA.
