A farmer has twice as maney chickens as cows.if the total number of animals is 30 how many chickens does the farmer have?
Answer (1)
Let’s solve it step by step.Let the number of cows be x.Then the number of chickens is 2x (since the farmer has twice as many chickens as cows).Total animals:$$x \text{ (cows)} + 2x \text{ (chickens)} = 30$$$$3x = 30$$$$x = 10$$So the number of chickens is:$$2x = 2 × 10 = \boxed{20}$$
