Which strategies can be used to solve this problem? Katie had 22 batteries. She used 2 batteries for her electric toothbrush. She used the rest of the batteries for her 5 clocks. Each clock uses the same number of batteries. How many batteries are in each clock? Choose all answers that are correct. A. Use objects to model the problem. Put 22 chips on a table. Remove 2 chips. Arrange the remaining chips into 5 equal groups. The amount in each group represents the number of batteries in each clock. B. Translate into an equation. (22 - 2) : 5 = b C. Work backward. Subtract 2 from 22 five times. The number that is left is the number of batteries in each clock. D. Use logical reasoning. Add the number of batteries used for her toothbrush to the number she used for each clock. Subtract the sum from 22 to get the number of batteries in each clock. (if picks two answers then i will mark as brainiest]
