Alright, lets get started.
In the question given that glacier receded 4 feet a day for a period of 25 days.
Which shows in 1 day, it recedes = 4 feet
means in 1 day, the height of the glacier gets shorter = 4 feet
So, in 25 days, the height of the glacier gets shorter = 4 * 25
So, in 25 days, the height of the glacier gets shorter feet
It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer
Hope it will help :)
The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1.
Step-by-step explanation:
The given is,
......................................(1)
....................................(2)
Step:1
By elimination method,
Subtracting Equations (1) and (2),
( - )
( ) + (
) = (
)
= 6
= 1
Step:2
Substitute the value of y in equation (1),
+ ( 3 × 1 ) = 5
= 5-3
= 2
Step:3
Check for Solution,
Substitute the values of x and y in Eqn (1),
2 + ( 3 × 1 ) = 5
5 = 5
Result:
The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1, by elimination method.
