He scale of a map is 1 cm : 80 km. what is the actual distance between two towns that are 5 cm apart on the map? he distance between the cities is km

Step-by-step explanation:

You can use a ratio for this:

So if you multiply 80 × 5, the divide by 1, you will get your answer.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
