Answer:
(D.) Commutative Property of Addition.
Step-by-step explanation:
The rule of Commutative Property of Addition is as follows:
a + b = b + a,
so in theory, if the case were 2 + 3 = 3 + 2, they would be the same.
And 71 + 3 = 3 + 71 because both are equal to 74 and it matches the a + b = b + a rule.
Since this is a proportion, we cross multiply.
12/2=9/x (The variable "x" is used the represent the unknown number, and this is the number we are solving for)
12*x=2*9 (Cross multiply)
12x=18 (Simplify)
x=18/12 (Divide each side by 12)
x = 3/2 (Simplify fraction)
The unknown number is 3/2, or 1.5.
