<h3><u>The value of the first number, x, is equal to 18.</u></h3><h3><u>The value of the second number, y, is equal to 90.</u></h3><h3><u>The value of the third number, z, is equal to 77.</u></h3>
x + y + z = 185
y = 5x
z = y - 13
Because we already have a value for y, we already have a value for z. We can now solve for a value of x.
x + 5x + 5x - 13 = 185
Add 13 to both sides.
x + 5x + 5x = 198
Combine like terms.
11x = 198
Divide both sides by 11.
x = 18
Because we have a value of x, we can solve for the exact values of y and z.
y = 5(18)
y = 90
z = (90) - 13
z = 77
I think that the angles of the polygon would not change since there isn't a change of the shape, rather it position and rotation. The sum of each internal angle is found using S = 180(n-2), so
S = 180(5-2)
S = 180(3)
S = 540
540 / 5 = 108 degrees.
Therefore, all angles in the polygon is 108 degrees. I think this is what you meant right?
Answer:
m = 2
Step-by-step explanation:
The number is positive because the line goes upward 2 units and right 1 unit.
All you have to remember is this. Reverse the operation. For example on this problem there is a -2 right? So reverse the operation and (REMEMBER:Always do what you did on one side to the other side) then you would have +2 on both sides. You do the same for variables and all of the numbers and result with 8x=2, so divide by 8 and get x=1/4
2 plus 3 plus 4 equals 9
So 2/9 chance you would get a blue marble
