Answer: X=2
2x plus 2x plus 3x equals 7x and then you add the +5 which means you now have 7x+5=6x+7 which you then solve from there by subtracting the 6x from the left side. You then get x+5=7 meaning x=2.
Answer:
133.33ft/hr
Step-by-step explanation:
Between 11am and 2pm, he had 3hrs
Height change 900 - 500 = 400ft
400/3 = 133.33ft/hr
What you would do is 30x5 which is 1500 and 14x12 which is 168
Then you would just divide 1500/168 and get (at most) 8
x = total amount of visitors
so we have 90% that lost $100, 9% that lost $1000, now 90+9 = 99%, what's left is just 1% then, so 1% won $10,000.
Profit is Revenue - Cost.
so the profit for the casino, is not who wins, because from the wins the casino needs to pay that to the winner, so they're losing that much, so for the casino, profits is when a player loses, so their profit will come from the 99% that lost money then.
keeping in mind that

since we know that 90% lost $100, that means 0.9x(100) is the total amount lost by all of them, since we also know that 9% lost $1000, then 0.09x(1000) is the total amount lost by them, and the wins are of course just 0.01x(100000).
