Simplify 5m - m - m +3

3m + 3

Explanation: If there's no coefficient in front of the variable, you can give it a coefficient of 1, so the -m can be thought of as -1m.

So our problem can be read as 5m - 1m - 1m + 3.

Now combine like terms.

Since 5m, -1m, and -1m are terms that contain an m, we can combine.

So 5m - 1m - 1m simplifies to 3m.

So our answer is 3m + 3

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
