Can someone please * help me answer these two algebra problems? I'm so confused! = [?
1.) A kayaker paddled 2 hours with a 6 mph current in a river. The return trip against the same current took 3 hours. Find the speed of calm water kayaker would. 2.) Tu Piggy Bank has 25 rooms in it, and some are quarters and nickels are. You have $ 3.45. How nickels? (I know you can understand this by trial and error, but you must write and solve equations.)
1. * Change time speed distance k == == Kayaker 2 (k +6) == 3 (K-6) == 3k 2k + 12 – 18 18 + 12 == 3k – check 2k k == 30: 2 (June 30) == 2 * 36 = = 72, 3 (30-6) == 3 (24) == 72. 2. Barrio == q, coins five cents n == n + q == == unmarked 5n + 25 25Q 345 (simply download the decimal point by multiplying the equation by 100) n == 25 – 25Q + 5 q (25 – q) == 345 + 25Q 20q 5q 125-345 345-125 == 220 == == == q 20q 220 / 20 == == == 11 n 25 to 11 November 14 ($ 0.25 ) + 14 ($ .05) 2.75 + 0.70 == == $ 3.45.
