Answer:
The train A weighs 137 tons and train B weighs 60 tons.
Step-by-step explanation:
We are given the following in the question:
There are two trains.
Train A and Train B.
Let x tons be the weight of train A and y tons be the weight of train B.
Total weight = 197 tons.
Thus, we can write the equation:
Train A is heavier than train B.
The difference of their weights is 77 tons.
Thus, we can write the equation:
Solving the two equations, we get,
Thus, the train A weighs 137 tons and train B weighs 60 tons.
When you want to find a percent of a number you do this:
given number/ 1 multiplied by percentage/100
so in this question its a multiple step
start with finding 25 percent of 4250 which is= 1062.5
so thats how much the discount is so the amount after the 25% discount is:
4250-1062.5= 3187.5
then you have to add 9% due to fees
so you find 9% of 3187.5 which is= 286.875
so you add 286.875 to 3187.5 gives you= 3437.375 in total cost for the vacation package
The y intercept and -4 and going down 2 and 1 right u til you reach the end of the graph

Arranging of books is an illustration of permutation and combination
There are 24 different possible arrangements she can make
<h3>How to calculate the number of arrangement</h3>
The number of books is given as:
n = 4
Take the factorial of both sides
n! = 4!
Evaluate
n! = 4 * 3 * 2 * 1
n! = 24
Hence, there are 24 different possible arrangements she can make
