You are allowed to move the decimal points before dividing with decimals because then, you will be able to divide by a whole number outside the dividend. Move the decimal point so that you are dividing by a whole number.

Answer: -1/3

Step-by-step explanation:

The formula is y2 - y1/ x2 - x1 . So the answer would be -1/3 bc 3 - 2 = 1 and -11 - (-8) = -3.

You will use 220ft of fencing to fence a rectangular plot of land. The length is 20 more than the width. What are the dimensions
PSYCHO15rus [73]
Set up the following equations:

L + W = 110
L - W = 20

110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.

We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:

2L = 130

Divide both sides by 2 to get L by itself:

L = 65

The length of the rectangle is 65 feet.

Plug this value into the second equation:

65 - W = 20

Add W to both sides:

65 = 20 + W

Subtract 20 from both sides:

45 = W

The width of the rectangle is 45 feet.

A bag contains a number of marbles of which 35 are blue, 10 are red and the rest are
photoshop1234 [79]

Answer:

Y = 45*p(y) / (1 - p(y))    if I knew what p(y) is, we can find how many yellow marbles there are.   p(y) = probability of choosing yellow.

Step-by-step explanation:

Total marbles =  35 + 10 + yellow

If probability of choosing yellow =p(y) = yellow/Total

p(y) =  Y/(35 + 10 + Y)

Solve for Y,

p(y)*(35 + 10 + Y) = Y

45*p(y) + p(y)*Y = Y

45*p(y) = Y - p(y)*Y

Y = 45*p(y) / (1 - p(y))
