1) Let Sean=x and Tyrone=y. But we want to get what Sean earns and
what Tyrone earns in terms of one variable so we say that Tyrone=x-4.5
(beacuse he makes $4.50 per hour less than Sean).
2) Now set up the equation: 8 hours time x plus 8 hours times x-4.5 equals 284 OR
8x+8(x-4.5)=284
3) Solve for x
8x+8(x-4.5)=284
8x+8x-36=284
16x=320
x=20
So Sean makes $20 per hour and Tyrone makes $15.50 per hour
D=number of drinks
p=number of bags of popcorn
75=6d+8p
100.50=12d+10p
multiply first equation by -2 and add to first
-49.50=-6p
divide -6
8.25=p
sub
100.50=12d+10p
100.50=12d+82.50
minus 82.50
18=12d
divide 12
1.50=d
$1.50 per drink

Answer:
Answer is D hope this helps :)
Step-by-step explanation:
I believe the the correct answer would be yes. Two lines can be drawn from a point that is not collinear with a certain line that will meet the line at a right angle or 90 degree angle and at an angle of 45 degrees. We can freely draw any line that would pass through a given point and would cross a given line at any direction giving us different angles and this would include a 90 and 45 degree angle.
