write an equation that represents the weights on the hanger. + = 2 a 1 9
Answer
Explanation:
Step1: Calculate the left - hand side weight
There are (2) weights of (a) and (1) weight of (1). So the left - hand side is (2a + 1).
Step2: Calculate the right - hand side weight
Count the number of (1)s on the right. There are (9) weights of (1), so the right - hand side is (9).
Answer:
(2a+1 = 9)
