Answer: x=63, y=52, z=48
Step-by-step explanation:
The complete question in english is:
The sum of 3 natural numbers is 163. By subtracting the third number from the sum of the first two numbers, we get 67. By subtracting the first number from the sum of the last 2 numbers, we get 37. Determine the 3 numbers
According to this we have a system with three equations and three unknown values:
(1)
(2)

Isolating :
(6) We have found the first number
Substituting (6) in (1):
(7)
Adding (7) to (3):
We have the following:
Isolating :
(8) This is the second number
Substituting (6) and (8) in (1):

Answer:
Squirrel will take 0.25 hours or 15 minutes
Step-by-step explanation:
Given:
Maximum speed of squirrel = 12 miles/hour
Distance to be covered = 3 miles
To Find:
Time taken to cover the distance = ?
Solution:
We are given the distance and speed of the squirrel and we have to find the time taken by the squirrel
We are given the formula for distance
Distance = speed * time
Now to we have the values
putting in the values
3 = 12 * time
dividing both sides by 12
0.25 hours = time
as one hour = 60 minutes
so
time = 0.25 * 60 minutes
time = 15 minutes
Squirrel will take 0.25 hours or 15 minutes
