Answer:
The girl had 24 candies in her bag.
Step-by-step explanation:
Since, regarding the girl's candies, 4 of them were blue, 1/6 of them were grape, 1/4 of them were watermelon, 1/3 of them were cherry and 1/12 of them were sour apple, to determine how many candies were in her bag, the following mathematical calculation should be performed:
1/6 + 1/4 + 1/3 + 1/12 = X
2/12 + 3/12 + 4/12 + 1/12 = X
10/12 = X
12/12 - 10/12 = 2/12
2/12 = 4
1/12 = 2
2 x 12 = 24
Thus, the girl had 24 candies in her bag.

Are these two lines parallel? Why or why not?
y=5x+6 and y=6x+5
Answer:
No
Step-by-step explanation:
The slopes of the equations are unequal, meaning the lines are not parallel and will eventually intercept

plz help me asap I just need to know the equation also it can be A) or C)
Answer:
C) Y=15X
Step-by-step explanation:
Y is the total donations and x is each free throw, every free throw, $15 is donated. For a it is saying no matter if there is a free throw or not $15 dollars is donated and b is saying the free throws depend on the total amount multiple by 15 which doesn't make sense

The slope of a line that passes through points (5, 14) and (-4, y) is 4/9. What is the value of y?
Answer:
slope=m=4/9
(x',y')=(5,14)
(x",y")=(-4,y)
we have
m=(y"-y')/(x"-x')
4/9=(-4-5)/(y-14)
4y-56=-81
4y=-81+56
y=-25/4
Answer: y = 10
Step-by-step explanation:
The slope of a line is the rise/run, so if you want to find the slope of a line between two points, you can take the change in y between the two points and divide it by the change in x.
The change in y would be (y2 - y1), where y2 is the y position of the second point and y1 is the y position of the first.
In a similar manner, to find the change in x, we can use (x2 - x1), where x2 is the x position of the second point and x1 is the x position of the first.
Now that we have the change in x and the change in y, we can make an equation to find the slope (which is change in y / change in x):
m = (y2 - y1) / (x2 - x1)
Now we can assign the points:
Point 1 is (5, 14)
Point 2 is (-4, y)
(Note: You could flip which point is which, and it wouldn't change the final answer, I'm just assigning these so you know where the x and y values are coming from when I plug the values into the equation)
Now that we have both points, we can plug the values into the equation:
m = (y2 - y1) / (x2 - x1)
m = (y - 14) / (-4 - 5)
m = (y - 14) / (-9)
There's one piece of information we haven't used yet, which will help us solve for the value of y. What we need to use is the slope (which is given to us as 4/9).
Plugging in the value of the slope will let us get y:
m = (y - 14) / (-9)
4/9 = (y - 14) / (-9)
-4 = (y - 14)
(Note: We're multiplying both sides by -9, don't forget about the negative sign)
-4 = y - 14
y = -4 + 14
y = 10
Solve for x
