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

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

ou would have 12 of each

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
