Let, the speed of boat = x
Speed of current = y
So, x + y = 280/7
x + y = 40 ---- first equation
x - y = 280/14
x - y = 20
x = 20 + y
Substitute this value of x in first equation,
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10
Substitute this in first equation,
x + 10 = 40
x = 30
In short, Speed of Boat = 30 mph, & speed of current = 10 mph
Hope this helps!
Answer:
- 2 2/7
Step-by-step explanation:
First, do the conversion:
[-(6*7)+3]/7 = -39/7
[(3*7)+2]/7 = 23/7
Then calculate the result:
23/7 - 39/7 = -16/7 or - 2 2/7
The slope is just the number attached to the x. The slope is 3/4.
Wouldn’t the answer be 48 if I’m correct because it’s talking about renting a bike for a hour and if you do the math 72-24 is 48 hours hope it’s right
Answer:
31
Step-by-step explanation:
In the above problem it is given that
No of Bees in the hive = 14
Number of bees in the garden = 17
In order to solve it
First of all I wrote 14 in the first box which represents the number of bees in the hive.
Secondly, I wrote 17 in the second box which represents the number of bees in the garden.
Now, in order to calculate the total number of bees i added the number in both boxes
Total Number of bees = 14 + 17
Total Number of bees = 31
So our total number of bees are 31
