Answer:
100
Step-by-step explanation:
We know that there are more goblins than magicians, by 20%.
Thus
be magicians M and goblins G, we have to:
G = 1 * M + 0.2 * M
G = 1.2 * M
M = G / 1.2
Therefore, knowing that in there are a total of 120 elves, replacing:
M = 120 / 1.2
M = 100
So there are 100 magicians in total in the club
Answer:
There are 100 wizards in the magic club.
Step-by-step explanation:
Let the number of wizards be represented by w
Number of goblins (g) = 120
Number of goblins (g) is more than number of wizards (w) by 20%
g = w + 20%w
120 = w + 0.2w
120 = 1.2w
w = 120/1.2 = 100 wizards

Answer:
See below.
Step-by-step explanation:
Total = 110
Let calls on third evening = x
second evening = 4x
first evening = x + 8
=> x + 4x + x + 8 = 110
=> 6x = 102
=> x = 17
First evening = x = 17 calls
Second evening = 4x = 68 calls
Third evening = x + 8 = 25 calls
Answer:
seven hundred and twenty nine
Answer:
x = 10
Step-by-step explanation:
Step 1: Write equation
3x - 8 = 22
Step 2: Add 8 to both sides
3x = 30
Step 3: Divide both sides by 3
x = 10
Answer:
9
Step-by-step explanation:
40 -100 = 60 and 60 percent of 15 is 9
82 tens in the same thing as 820 because if you multiply 82 by 10 you get 820
