Answer:
Step-by-step explanation:
this is the same equation, the system has infinitely many solutions
Answer:
A
Step-by-step explanation:
The other situations do not represent a 60% probability.
B is a situation in which 40% of people prefer aisle seats.
C is a situation in which 33% of people prefer aisle seats
D is a situation in which 66% of people prefer aisle seats.
A² + b² = c²
20² + n² = (n+2)²
400+ n² = (n+2)(n+2)
400 + n²=n² + 2n + 2n +4
400 + n² = n² +4n +4
400 + n²-n² = n²-n² + 4n+4
400 = 4n + 4
400-4 = 4n +4-4
396 = 4n
396/4 = 4n/4
n= 99
20²+ 99² = (99+2)²
400 + 9801 =10201
10201=10201
Answer:
The amount of punch mix to use is 3/4 gallons
Step-by-step explanation:
Let
x ----> parts of water
y ---> parts of punch mix
we know that
----> equation A
That means ---> The parts of water is 8 times the parts of punch mix
If we have 6 gal of water
then
substitute in the equation A
solve for y
Simplify
therefore
The amount of punch mix to use is 3/4 gallons
