Step-by-step explanation:
The four fours problem is one of the problems given in the book "The Man Who Calculated" by Malba Tahan, a Brazilian-born professor of mathematical sciences.
There are many complicated problems in this book made with the intention of using logic to find a value.
The 4 fours problem is based on using these numbers and using any operation to result in the numbers 1 through 10.
Answer:
The reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
Step-by-step explanation:
Definition of Reflexive Property of congurence
The meaning of Congruence is figure has the same size and shape. If you were comparing something to itself, then it definitely have the same size and shape this is called Reflexive Property of congurence .
By using Reflexive property of congurence .
RST = RST
Therefore reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
X=number of adults, y= number of students
x+y=12
18x+12y=162
You can simplify the second equation by dividing by six: 3x+2y=27
Rearrange the first equation: y= 12-x. Plug y into the simplified second equation:
3x+2(12-x)=27
3x-2x+24=27
x=3.
Plug the now known x value into y=12-x. So y= 9.
Therefore, there are 3 adults and 9 students.
