Step-by-step explanation:
I am not positive if the experimental probability questions are correct, since it has been a while since I've done this, but the theoretical questions should be right. This is because there are 4 kings in every deck and there is replacement. Also, there are 13 hearts in each deck and there is replacement.

75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multiply both sides by 4
640=original cost
answe ris $640 =original cost
One simple trick here is that 25% is one third of 75%. So all you need to do is MULTIPLY $160 by 4 to get how much the camera's regular price was.
160 x 4 = 640
The camera's regular price was $640.00

x---------> the length side of rectangle
y---------> the width side of rectangle
we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2
28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m
the answer is
the length side of rectangle is 240 m
the width side of rectangle is 120 m

The equations you need to solve are:
x + y = 30
x - y = 2 ==> (redefine in terms of y) y = x - 2
substitute into first equation
x + x - 2 = 30
2x = 30 + 2
x = 32/2 = 16
16 + y = 30
30 - 16 = y = 14
x = 16
y = 14
And that's how that is done.
The correct answer is:
The numbers are 14 and 16.
Explanation:
Let x and y represent the numbers. Since the sum of the numbers is 30, this gives us the equation
x+y = 30.
Since the difference of the numbers is 2, this gives us the equation
x-y = 2.
This gives us the system
To solve this, we will eliminate one variable. Since the coefficients are all the same, but the y-variables have different signs, we will eliminate them by adding the equations together:
Divide both sides by 2:
2x/2 = 32/2
x = 16.
Substitute this back into our first equation:
16+y=30
Subtract 16 from each side:
16+y-16=30-16
y=14
