The bus fare is x, and the ferry fare is y.
x + y = 8
The bus fare will increase by 10% and the ferry fare will increase by 25%.
1.1x + 1.25y = 9.25
Multiply the first equation by -1.1:
-1.1x - 1.1y = -8.8
Add this to the original second equation.
0.15y = 0.45
y = 3
x + y = 8
x + 3 = 8
x = 5
The bus fare is $5, and ferry fare is $3.
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:
-6
Step-by-step explanation:
The equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The y intercept is the value when x = 0
The y value is -6 when the x value is 0
y = -4x+ (-6)
Step-by-step explanation:
add up all of the numbers in the five groups then divide the numbers by the number of numbers you have for example if the sum of all of those numbers is let's a 25 and you have 5 numbers you'll divide 25 by 5 and your men will be 5:00 and if the sum of the numbers was 30 and you have six numbers you'll / 30by6 then your answer then the mean will be six
