Answer;
x = 7
Step-by-step explanation:
3(x - 1) - 4(5 - x) = 2(6 + x)
3x - 3 -20 + 4x = 12 + 2x
7x - 23 = 12 + 2x
7x - 2x = 23 + 12
5x = 35
x = 35/5
x = 7
It is C.
1 times 48 is 48.
2 times 24 is 48
3 times 16 is 48
4 times 12 is 48
6 times 8 is 38.
168 is the area, because if you want to find the area of something, you could multiply the numbers, to find the area.
Hope this helps :)
We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour
ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph
