Distributive property :
a (b+c) = ab + bc
Try writing 47 = 50-3 or 47 = 40+7.
11 x 47 = 11 x (50-3) = 11 x 50 - 11 x 3 = 550 - 33 = 517
or
11 x 47 = 11 x (40+7) = 11 x 40 + 11 x 7 = 440 + 77 = 517
In this example, y is equal to 8.
In order to find this, first note that the two x value expressions create a straight line. That means when we add them together they will equal 180. this will give us a value for x.
x + 10 + 10x - 61 = 180
11x - 51 = 180
11x = 231
x = 21
Now that we have the value of x, we can do the same for the straight line created by the x + 10 angle and the 18y + 5 angle.
x + 10 + 18y + 5 = 180
(21) + 10 + 18y + 5 = 180
36 + 18y = 180
18y = 144
y = 8
I think you mean roll a die. To do this you would find the number of non-even numbers and divide that number by the total amount of numbers on the die. On a normal six-sided die these numbers would be 1,3,and 5, so your probability of not rolling an even number would be 50%
well, clearly the LCD from the denominators of 5 and 10 is just 10, thus
