75% of 500 is 375
so there are 375 seats filled.
so that mean's there 125 seats left
Answer:
a/1/$400
Step-by-step explanation:
240 divided by 12=20
20x10x2=$400
The correct answer is {1, 2, 5, 6}.
A intersect B would be {3, 4}; the complement of this is everything else.
Answer:

Step-by-step explanation:
Given:
The equation of the known line is:

A point on the unknown line is (-4, 4)
Now, since the two lines are parallel, their slopes must be equal.
Now, slope of the known line is the coefficient of 'x' which is
.
Therefore, the slope of the unknown line is also 
Now, for a line with slope 'm' and a point on it
is given as:

Here,
. Therefore,

Hence, the equation of the unknown line is
.
Try dividing both sides by 2.
Hope i helped :)
(It's kinda cool, because by dividing both sides by 2 we get !<3u :)
