Its three because three divided by two times three plus equal 13.5
Answer:
Boat = 20 mph
Current = 5 mph
Step-by-step explanation:
If b is the speed of the boat, and c is the speed of the current, then:
b + c = 225 / 9 = 25
b − c = 225 / 15 = 15
Solve the system of equations with elimination.
2b = 40
b = 20
Plug back into either equation to find the speed of the current.
c = 5
Answer:
Step-by-step explanation:
8.2 comes between 8 and 9
8.2 =
.
As you know, the interval between 8 and 9 is divided into 10 equal parts and each part is 1/10 or 0.1.
Step-by-step explanation:
(2b-3)/(b-2)(b+2) = 3b(b-2)/(b+2)(b-2)
2b²+4b-3b-6/b²-4=3b²-6b/b²-4
2b²+b- 6= 3b²-6b
move square to square unknown to unknown
-b²+7b-6/b²-4
i also dk this is true or false
