The opposite is a negative so the answer would be -6
$210.67 is the answer. Rounded, of course, from 210.666666667
Answer:
X= -5
y= -9
Step-by-step explanation:
7x -4y = 1
4(5x -y = -16)
(7x - 4y = 1) - (20x -4y = -64)
X= -5
y= -9
So,
Proportion basically means, that something is proportional
Example: A rope's length and weight are in proportion.
It's in proportion because the longer the rope, the more the weight
so, let's say
A popcorn machine costs 20 an hour
And in order to rent one, you have to pay $32 dollars
So you pay 32 for the machine, then 20 for every hour you use it
the number of hours used WOULD be proportional to the cost because
the more hours used, the more the cost
your final answer: YES it is proportional
