Three siblings are comparing their ages. Jenna is the youngest. Her brother Carl is 6 years older than her. Her sister Eve is twice her age. The sum of their ages is 42. Let j represent Jenna's age. (a) Write expressions for both Carl's age and (b) Write and solve an equation for j. Then Eve's age in terms of j. state the ages of all three siblings. Jasper is 43 years old and his daughter Freya is 7. In n-years Jasper will be four times as old as Freya is at that point. Set up and solve an equation for n. Then state both Jasper and Freya's ages after n-years.
