No because to get a proportional relationship you have to add the same number to all x to get y
Option D is the correct answer
3/7 = 9/x
cross multiply because thats how u solve proportions
(3)(x) = (7)(9)
3x = 63
x = 63/3
x = 21
and if u will notice : 3/7 and 9/21 ....9/21 reduces to 3/7....so these are equivalent fractions...because proportions are nothing but equivalent fractions
The answer is B.
The commutative property enables you to switch around the numbers in addition or multiplication. B does this correctly and simplifies the answer correctly, giving you 1,800.
