What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

From the given information let the length of the blue ribbon be 'x' inches.

Therefore, The length of the red ribbon is (x - 7) inches.

When The length of the blue ribbon is 10 inches meaning 'x' is 10 inches.

So, the length of the red ribbon is (10 - 7) = 3 inches.

When, x = 27,

The length of the red ribbon is 27 - 7 = 20 inches.

When the length of the blue ribbon is 'x' inches the length of the red ribbon would be (x - 7) inches.
