On a map the length of a lake is 4.5 centimetres. The actual length of the lake is 2.7 kilometres. Write the scale of the map as a ratio in the form 1 : n.

1:60000

Step-by-step explanation:

Make sure the units match by converting 2.7km to 2700000cm. Divide 2700000 by 4.5 to get 60000. So, every 1cm on the map is 60000cm in real life

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
