Since x+y equals 5 that means x is 3 and y is 2 because 3+2=5. So now plug it in, 2(3)+3(2). Two multiplied by three is 6 and three times two is 6. So now it’s 6+6 which equals 12. So it’s 2(3)+3(2)=12
Answer:
y = 3
Step-by-step explanation:
Answer: 3/6 + 4/6
Step-by-step explanation:
So the key to this is you can only add fractions with the same denominator. As you can see from this question these denominators (2 and 3) are not the same so we need to change that. We can usually find a common denominator between the numbers but to save time the smallest number that both 2 and 3 go into is 6. so 1/2 becomes 3/6 because 1/2=3/6. And 2/3 becomes 4/6 because 4/6=2/3. Since that's true we can add both 3/6 and 4/6. So when adding fractions remember only add NUMERATORS do not add DENOMINATORS. so 3/6 and 4/6 = 7/6 NOT 
7/12.
Given: In ΔDEF and ΔDGF, Side DF is common.
To prove congruent of the triangle, we must require the minimum three conditions; like two sides and one angle of one triangle should be equal to the other triangle. OR Three sides of one triangle should be equal to the other triangle. OR Two angles and one side of one triangle should be equal to the other triangle. etc.
As per given question, to prove congruent of given triangles by SAS property then we should have given two sides and one angle of one triangle should be equal to the other triangle as additional information.
Since, In ΔDEF and ΔDGF, Side DF is common. So, we should require only one side and one angle that should be equal to another triangle.
There are 24 ways in which 5 guys can sit if arranged from oldest to youngest.
We have,
Five guys.
Now,
We know that,
Total number of ways to arranged around a table (n) = (n-1)!
So,
For n = 5,
I.e.
(n - 1)! = (5 - 1)! = 4!
So,
Total number of ways to arranged Five guys rom oldest to youngest (n) = (n-1)!
i.e.
= (5 - 1)! = 4!
We get,
= 4 × 3 × 2 × 1
i.e.
Total number of ways to arranged Five guys rom oldest to youngest (n) = 24.
Hence we can say that there are 24 ways in which 5 guys can sit if arranged from oldest to youngest.
