Answer:
i say d
Step-by-step explanation:
When ur variables cancel and ur left with a true statement...equal statements, such as 0 = 0 or 6 = 6, then u will have infinite solutions. So the answer to this is infinite solutions.
** now if u were left with 0 = 3 or 2 = -2....then there would be no solutions.
if u ended up with x = 7 or y = 5....a variable equal to a number, then there is 1 solution
That what the answer is because on what is asking the answer is gonna be 6,1761
Answer: 20%
Step-by-step explanation:
20% black dresses or suits
.35 = 35% wearing brown
1/4 = 25% wearing navy
100% -20% - 35% - 25% = 20% left
The angle between the legs of length 16 and 18 has measure 90 + 55 = 145 degrees.
Now use the law of cosines: it says 
satisfies
and solving for gives
so the answer is C.
