189 because 20.7 rounds to 21 and 9.18 rounds to 9
21 * 9 = 189
Letter A is the answer because
4y = 15 - 3x
so y = 15/4 -3x/4
Answer:
The relationship in this equation is linear, but not proportional. If it was proportional, then replacing x with nx should give ny as the answer. Example:
y = 3x
Replace x with 2x.
y' = 3(2x) = 2(3x) = 2y
y' = 2y
This is proportional. But if you replace x with 2x in
y = 3x + 5,
you will not get 2y for y'. This case is not proportiona
