Answer:
the last one
Step-by-step explanation:
So, looking at how many seniors there are, you can see that there are 35 of them. 25 are in sports, 5 are in music/drama, and 5 work. If you added them altogether, you get 35. Now, the chance of them being in sports is 25/35 chance/probability. You can simplify 25/35 because both of them are divisible by 5. 5 times 5= 25 and 7 times 5=35. Therefore, the answer is 5/7.
Answer:
X= 2.5 Y= 3.5
Step-by-step explanation:
2X+3Y =15.5
replace either x or y with your second equation
(2*(6-y))+3y=15.5
now you only have one variable
12-2y+3y=15.5
y=3.5
now insert your y value into the second equation provided
x+y=6
x+3.5=6
so x= 2.5
you can check your answer by inserting these numbers into the equations and it should work
38.71428571428571 or 38.7
