Answer:
17/12= 1 5/12
Step-by-step explanation:
Common denominator:
2/3= 8/12
3/4= 9/12
Solve:
8+9= 17
17/12= 1 5/12
Answer: 564480 arrangements
Step-by-step explanation:
First, let's consider the French and English delegates as one party because they will sit next to each other.
So total delegates if French and English are always together comes out to be 9 instead of 10.
Now, they are to sit in a row and can have different seats so the total number of ways they can sit is= 2 x 9!= 725760 ways.
Now, when Russian and U.S delegates are not to sit next to each other so consider similarly like before consider them as one unit like French and English. Now they can also change their seats so number of way for them= 2 x 2 x 8!= 161280 ways
To find out when French and English delegates are together and Russain and U.S delegates are not together we subtract the way from the original value.
725760-161280= 564480 way.
Congruent means they are the same,
A and Q are both the first letters, which mean they would also be the same.
Set the two equations equal to each other, solve for x then solve for angle A.
x-10 = 2x-30
Add 30 to each side:
x+20 = 2x
Subtract 1x from each side:
x = 20
Now replace x with 20 in the equation for A
A = 20-10
Angle A = 10 degrees.
