$250 + 50x = $200 + 60x
Get like terms on the same side using subtraction
250 -200 + 50x = 60x
50 + 50x - 50x = 60x -50x
50 = 10x now divide by 10 and get 5 days.
Let's check
Day 1 Actor A is $250 + 50 = $300 Actor B = $200 + 60 = $260
Day 2 Actor A is $250 + 100 = $350 Actor B = $200 + 120 = $320
Day 3 Actor A is $250 + 150 = $400 Actor B = $200 + 180 = $380
Day 4 Actor A is $250 + 200 = $450 Actor B = $200 + 240 = $440
Day 5 Actor A is $250 + 250 = $500 Actor B = $200 + 300 = $500
Step-by-step explanation:
-3x - 7y = -63
-(3x + 7y) = -63
3x + 7y = -63/-1
3x + 7y = 63
Value of x
3x + 7y = 63
3x = 63 - 7y
x = (63 - 7y)/3
Value of y
3x + 7y = 63
7y = 63 - 3x
y = (63 - 3x)/7
Answer: 
=========================================================
Explanation:
Use the pythagorean trig identity
and plug in the fact that 
Isolating sine leads to
. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
