Idon’t really know about inequalities can y’all ?

Step-by-step explanation: I don’t really know about inequalities can y’all help?

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
