Why do some mammals bear only one offspring Some mammals only have one offspring because they may only be able to handle having one without hurting themselves
Problem solving on System of Linear Equations 1. One angle is two degrees more than its complement. Find the measures of the two complementary angles. 2. JM is twelve years older than his brother PJ. Four years from now, PJ will be two-thirds as old as JM will be four years from now. How old are they now? 3. Rey has two investments that earn an annual income of Php49,800. One investment yields 7% interest and the other 8%. How much is invested at each rate if the total amount invested is Php640,000. Answer: 1. 44 and 46 2. PJ is 20, JM is 32 3. Investment with 7% interest = 140,000 ; Investment with 8% interest = 500,000 Step-by-step explanation: 1. x = 1st angle x +2 = 2nd angle Completentary angles are equal to 90 degrees x + (x + 2) = 90 2x + 2 = 90 2x = 90 - 2 2x = 88 x = 44 (44) + 2 = 46 2. Let x = Age of PJ x + 12 = Age of JM 2/3(x + 12 + 4) = x + 4 2/3(x + 16) = x + 4 (2x+32)/3 = x + 4
