If they were to win $30 they would expect to get $27 in profit.
If they were to win $10 they would expect $7.
If they were to win $0 they would expect $-3 in profit, so technically if they win nothing they lose money.
Hope I could help! :D
First, transpose the constants to the right side just like an ordinary equation, but leave the inequality sign as it is. That becomes
x - 72 > -96
x > -96 + 72
x > -24
Thus, just check among the choices which are greater than -24. The answers would be D and E.
Answer:
Step-by-step explanation:
4(2x+12)=0 work the () first
8x+48=0 subtract 48 to both sides to get the x by itself
8x=-48 divide by 8
x= -6
The answer is 8 1/2! Hope this helped :)
Answer:
The first plane is moving at 295 mph and the second plane is moving at 355mph.
Step-by-step explanation:
In order to find the speed of each plane we first need to know the relative speed between them, since they are flying in oposite directions their relative speed is the sum of their individual speeds. In this case the speed of the first plane will be "x" and the second plane will be "y". So we have:
x = y - 60
relative speed = x + y = (y - 60) + y = 2*y - 60
We can now apply the formula for average speed in order to solve for "y", we have:
average speed = distance/time
average speed = 1625/2.5 = 650 mph
In this case the average speed is equal to their relative speed, so we have:
2*y - 60 = 650
2*y = 650 + 60
2*y = 710
y = 710/2 = 355 mph
We can now solve for "x", we have:
x = 355 - 60 = 295 mph
The first plane is moving at 295 mph and the second plane is moving at 355mph.
