because to make the denominator to 100, you need to multiply 10 by 10 which is 100.
and because you multiply 10, you also have to multiply the numerator by 10.

Answer:
B. 100
Step-by-step explanation:

143-13=130
10x=130 divide both sides by 10 130/10= 13 x=13
MN=7(13)=91+9=100
LN=3(13)=39+4=43
100+43
Eh I would personally say that your getting more if you do 96 it is more expensive but don’t get 64
C. Table T
It is not a function if one x value gives more than 1 y-value. In table T, 3 gives 4 and -4 two different y values.
