What property justifies that 6x+9/3 =2x + 3? (see the pic of how the fraction is)
spayn [35]

Answer:

C. Distributive property

Step-by-step explanation:

Distributive property says that

a\cdot (b+c)=a\cdot b+a\cdot c

Consider left part of the expression

\dfrac{6x+9}{3}=\dfrac{1}{3}\cdot (6x+9)

By distibutive property,

\dfrac{1}{3}\cdot (6x+9)\\ \\=\dfrac{1}{3}\cdot 6x+\dfrac{1}{3}\cdot 9\\ \\=2x+3

\text {x - coordinate = }  \bigg( 5\dfrac{1}{2}  +  3\dfrac{3}{4} \bigg) \div 2

\text {x - coordinate = }  \bigg( 5\dfrac{2}{4}  +  3\dfrac{3}{4} \bigg) \div 2

\text {x - coordinate = } 8\dfrac{5}{4}   \div 2
