Halle has two ribbons. The blue ribbon is 58 cm. The green ribbon is 38 cm longer than the blue ribbon.How long is the green ribbon?

Halle uses 67 cm of the green ribbon to wrap a present.
How much green ribbon is left?

Answers

The green ribbon is 96 cm long and if 67 cm of the green ribbon is used to wrap a present, the amount left is 29 cm

An equation is an expression that shows the relationship between numbers or variables.

Let x represent the length of the green ribbon.

The green ribbon is 38 cm longer than the blue ribbon, hence:

x = 58 cm + 38 cm

x = 96 cm

The green ribbon is 96 cm long.

If 67 cm of the green ribbon to wrap a present, the amount left is:

Amount left = 96 cm - 67 cm = 29 cm
