Just subtract 9:00-2:30 so your answer should 6 hours and 30 minutes or 6 1/2 hours
Answer: B) Infinitely many solutions; both equations are equivalent
==============================================================
Work Shown:
x+y = 4 ... start with the first equation
x + (-x+4) = 4 ... replace y with (-x+4)
x-x+4 = 4
0x+4 = 4
0+4 = 4
4 = 4 ... this is a true statement regardless of what x you pick
So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.
Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.
7/25, 6/25, and 11/50. Looks like they are already in order, or you meant to do that...
Answer:
False
Step-by-step explanation:
A subset is a set whose elements belong to another set
If B is a subset of A, B would contain elements of A
For example, A = {a, b, c} and if B is a subset of A , B = { a, b}
