Answer:
x=4
Step-by-step explanation:
5x+20-13=2x+19
3x+20-13=19
3x+7=19
3x=12
x=4
101/2 is 50 1/2
23/8 is 2 7/8
50 1/2 - 2 7/8 = 47 5/8
47 5/8 / 1 2/3 = 27.69, to the nearest hundredth
Since he can't make fractions of picture frame, the answer is 27
Answer:
The second years payment is 17689.
Step-by-step explanation:
If the first year is $10,205 then you subtract 10205 from 27894 which is 17689.
Equation: $27894-$10,205= $17689

5m^5n^4
Step-by-step explanation:
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.
