Solution:
Total number of students=273
Let x students choose Tiger. Then we can write
Number of students who choose Bulldog 
Number of students who choose Lion 
So we can write

Hence a total of 39*2=78 student choose Tiger.
Answer:
x=9 y=-4
Step-by-step explanation:
1) to eliminate a variable make sure they are the same so you can cancel them out
lets eliminate x
-3 and -2 share a GCF of 6 so
2(-3x-4y=-11)
-6x-8y=-22
3(-2x-6y=6)
-6x-18y=18
-6x-8y=-22
-
-6x-18y=18
--------------------------
10y=-40
y=-4
2)substitute y as -4 in the second equation
-2x-6(-4)=6
-2x+24=6
-2x=-18
x=9
Answer:
95$
Step-by-step explanation:
Alli sells 5 bars, for each bar she earnd 5$ so she earns 5*5=25$
Janet sells 7 mugs, and for every mug she earns 10$ (twice then Alli), so she earns 7*10=70$
Together: 25+70=95$
There is not a formula for everything need more data
Answer:
C
Step-by-step explanation:
The formula for finding the distance between 2 points (x1, y1) and (x2, y2) is
d = √[(x2 - x1)² + (y2 - y1)²]
Here (x2, y2) = (2, 3) and (x1, y1) = (4, -3)
Plugging them gives us
d = √[(2 - 4)² + (3 - (-3))²]
d = √[(2 - 4)² + (3 + 3)²]
