Y is 15 and x is 14 mark me as brainless
$1 = 3.70 rands
$450 is simply 450 times $1, so multiply the conversion equation above by 450 on both sides.
450 * $1 = 450 * 3.70 rands
$450 = 1665 rands
-12.4 has the greatest value among these numbers
3. y=-2/3x-4
4. y=4
5. y=x+5
You work out unit rates by making the denominator 1
