Question

the length of a line is y centimetres
write down an expression in terms of y for the length of the line in millimeters

Answer 1

Answer: 10y

Step-by-step explanation:

First and foremost, we should note that: 1 centimeter = 10 millimeters.

Since the length of the line is y centimetres, the expression in terms of y for the length of the line in millimeter will be:

= y × 10

= 10y

For example, if the length is 3cm, it'll then be: = 10y = 10 × 3 = 30 millimeter
