Answer:
The required probability is, 
Step-by-step explanation:
Of 24 employees at a local supermarket, 13 work as cashiers and 11 stock shelves. If 4 employees are selected at random to work overtime, then
P( all 4 are cashiers) = 

If we discuss this as if it is a triangle then the "rise" is the vertical side and the "run" is the adjacent side.
So the ratio of the rise to the run is 8 / 15 which equals

Use elimination and subtitution method to solve the problem.
First, eliminate x and you'll find the value of y
x - 4y = 12
x - y = 0
--------------- - (substract)
-3y = 12
y = 12/-3
y = -4
Second, subtitute -4 as y and you'll find the value of x
x - y = 0
x- (-4) = 0
x + 4 = 0
x = -4
The solution
x,y = -4,-4

Answer:
C. 48x = 32
Step-by-step explanation:
For which equations does the fraction 2/3 make the equation true? Choose all that apply
Solving
A. 35x =20
x = 20/35
x = 4/7
B. 26x=18
x = 18/26
x = 9/13
C. 48x = 32
x = 32/48
x = 2/3
D. 22x =14
x = 14/22
x = 7/11
The correct Option is Option C
