7-46.

Last month, a dwarf lemon tree grew half as much as a semi-dwarf lemon tree. A full-size lemon tree grew three times as much as the semi-dwarf lemon. Together, the three trees grew 27 inches. Write and solve an equation to determine how much each tree grew. Make sure you define your variable. Homework Help ✎

Let *x* = growth of the semi-dwarf tree.

Now write expressions for the growth of the dwarf and full-size trees.

Growth of full-size lemon tree: 3*x*

Growth of dwarf lemon tree: 0.5*x*

*x* + 0.5*x* + 3*x* = 27

Semi-dwarf tree grew 6 inches.

Dwarf tree grew 3 inches.

Full-size tree grew 18 inches.
