Answer:
20 = 4n
n = 5
Step-by-step explanation:
Given that :
Number of gifts Keiko wrapped = 20
Let number of gifts wrapped by Henry = n
Keiko wrapped 4 times as many gifts as Henry
Hence,
20 = 4n
The equation that relates the number of gifts wrapped is :
20 = 4n
To obtain n ;
Divide both sides by 4 to isolate n
20/ 4 = 4n / 4
5 = n
Hence,
n = 5
Good luck!
I hope you do good
Answer:
Current Speed = 2 miles per hour
Step-by-step explanation:
Let speed of boat be x (or 44)
and speed of current be c
With current, the speed is x + c
against current the speed would be x - c
We know D = RT
D is distance
R is Rate
T is time
We can write 2 equations as:
(x + c)t = 276
and
(x - c)t = 252
Replacing x with 44, we get:
(44 + c) * t = 276
(44 - c) * t = 252
We can solve for t in both and equate them together and find c (speed of current):
t = 276/(44+c)
t = 252/(44-c)
Now, we have:
The speed of current is 2 mph
