$\text{You're going to need to combine like terms to get your answer}\\\\\text{Add or subtract the like terms:}\\12x+3y-9x\\\\\text{12x and -9x are like terms, so solve:}\\\\3x+3y\\\\\text{There are no more like terms, so your answer would be 3x + 3y}\\\\\boxed{3x+3y}$

The answer is 6x

You have to add 12 and 3 which is 15 then you have to do 15 minus 9 then it is 6 then you will put the x there because it had 2 x and 1y so 6x is the answer

The map below shows the path that Jin walked this morning. According to his pedometer, the total distance of this path was 2.3 k

Answer:

5 centimetres = 1 kilometre

Step-by-step explanation:

First add up the distances measured on the map.

1.1+4.8+2.2+3.4=11.5 cm

Based on this, since the number of cm is greater than the number of km, we can figure out that each cm should not be multiplied to get the km, so we can eliminate the first two answers.

Next write an equation to represent finding the scale

x=scale

11.5=2.3x

Now solve for the scale

11.5/2.3=2.3x/2.3

5=x

Therefore the scale is 5 centimetres = 1 kilometre
