X + 4/5 = 11
x = 11 - 4/5
x = 55/5 - 4/5
x = 51/5 or 10 1/5
or u can do it this way..
x + 4/5 = 11.....multiply everything by common denominator of 5
5x + 4 = 55
5x = 55 - 4
5x = 51
x = 51/5 or 10 1/5
Answer:
which agrees with option A in the list of possible answers

A vertical compression by a factor 9 is represented by the transformation:

Therefore the answer to the problem is:

It is 48 cm together because mutiply it
You can just do the inverse operation. 39 divied by 10 = 3.9
so 3.9 *10 =39
hope it helped
