Step-by-step explanation:
=> 
<u><em>Where a = 2, b = 3</em></u>
=> 
=> 4(4) - 4(6) + 9
=> 16 - 24 + 9
=> -8 + 9
=> 1
The required simplified value of b + g is 21.
Given that,
At a classroom costume party, the average age of the b-boys is g, and the average age of the g girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42- year-old teacher) is b+g,
<h3>What is average?</h3>
The average of the values is the ratio of the total sum of values to the number of values.
Here,
The average age of the b-boys is g.
The average age of the g-girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42-year-old teacher) is b+g,
Now,
average of n = 3 (b , g , b+g)
Average = g + b + 42 / 3
b + g = (b + g + 42 ) / 3
3b + 3g = b + g + 42
3b - b + 3g - g = 42
2b + 2g = 42
2 (b + g) = 42
b + g = 21
Thus, the required simplified value of b + g is 21.

This is a basic subtracting problem.
$84.00 minus $29.00
Debit means it's been taken out of the bank account, so subtracted.
After subtracting the balance will be $55.00.
You can double check your work by adding 55 + 29 = 84.
Answer:
N = 1680
Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'
Step-by-step explanation:
Given the word 'champion' which is an 8 distinct Letter word. The number of 4 letter groupings that could be formed from it can be given by the permutation since in this case order of letters are important.
The number of distinct 4 letter groupings can be given as;
N = nPr = 8!/(8-4)!, where n= 8 and r = 4
N = 8P4 = 8!/(8-4)!
N= 8!/4!
N = 1680
Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'
We know that 1 gallon = 4 quarts and 1 quart = 32 ounces.
We have 4 quarts of lemon and it is 1 gallon ( and we also have 1 gallon of water ). Also we have 32 ounces of honey, which is 1 quart more.
4 quart + 4 quart + 1 quart = 9 quarts = 2 gallons 1 quart
Answer:
There is 9 quarts or 2 gallons and 1 quart of lemonade.
