The number of trees planted by the alpine Nursery in April was three more than twice the number of trees planted by the nursery

Readme [11.4K]

Answer:

There were 34 trees planted in March

Step-by-step explanation:

* Lats explain how to solve the problem

- The number of trees planted by the alpine Nursery in April was

three more than twice the number of trees planted by the nursery

in March

- Assume that the number of trees planted in March is x

∵ The number of trees in April was three more than twice the

number of trees on March

∵ The number of trees on March was x

∴ The number of trees in April = 2x + 3

- There were 71 trees planted in April

∵ The number of trees were planted on April was 71

∵ The number of trees in April = 2x + 3

∴ 2x + 3 = 71

- Subtract 3 from both sides

∴ 2x = 68

- Divided both sides by 2

∴ x = 34

∵ x represents the number of trees were planted in March

∴ There were 34 trees planted in March
