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:
x = 3 or x = 2 or x = -1 or x = -5
Step-by-step explanation:
Solve for x:
((x - 3) (x - 2) (x + 1) (x + 5))/x = 0
Multiply both sides by x:
(x - 3) (x - 2) (x + 1) (x + 5) = 0
Split into four equations:
x - 3 = 0 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0
Add 3 to both sides:
x = 3 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0
Add 2 to both sides:
x = 3 or x = 2 or x + 1 = 0 or x + 5 = 0
Subtract 1 from both sides:
x = 3 or x = 2 or x = -1 or x + 5 = 0
Subtract 5 from both sides:
Answer: x = 3 or x = 2 or x = -1 or x = -5
Answer:
$126,000
Step-by-step explanation:
16% of 150,000 is 24,000
150,000-24,000=126,000
Y=-4x+3 is already in slope intercept form. Graphed it looks like this
