Answer:
Shane had $240 at the beginning of his trip.
Step-by-step explanation:
Shane returned from a trip to Las Vegas with $420 and this is 75% more of at the beginning.
Let us assume the money he carried at the beginning of the trip was $x
At present he is having 75% more means total money he has = x+75% of x
This total amount is equal to $420
Therefore x + .75x = 420
x(1 +.75) =420
1.75 x = 420
Now by dividing both sides by 1.75
x = 420÷1.75
= $240
Therefore the amount he carried in the beginning of the trip is $240.
Answer: the 1 one
Step-by-step explanation:
Rewrite the system of equations in matrix form.
This system has a unique solution 
so long as the inverse of the coefficient matrix 
exists. This is the case if the determinant is not zero.
We have
so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.
2.25/0/00075 = 3000
There will be 3000 sheets of paper
the total height of the stack is 2.25
