What’s the value of x? :/

kolbaska11 [484]

Answer:

$x = 27$

Step-by-step explanation:

According to congruent chords and arcs theorem, if $\overline{XY} \cong \overline{ZY}$ then $\arc{XY} \cong \arc{ZY}$ .

This means that $\arc{XY} = \arc{ZY} = (6x - 20) degrees$

Thus:

$\arc{XY} + \arc{ZY} + \arc{ZX} = 360$ (full circle = 360°)

$\arc{XY} = (6x - 20)$

$\arc{ZY} = (6x - 20)$

$\arc{ZX} = 76$

Plug in the values into the equation

$(6x - 20) + (6x - 20) + 76 = 360$

$6x - 20 + 6x - 20 + 76 = 360$

Add like terms

$12x + 36 = 360$

Subtract 36 on both sides

$12x = 360 - 36$

$12x = 324$

Divide both sides by 12

$x = 27$

What is the probality of rolling a sum of 5 if two regular 6 -sides number cubes are rolled

Dmitry [639]

Each die has six numbers, the total number of possible combinations is 6 * 6 = 36

The combinations in which you can get a sum of 5 are: 1 &4, 2 & 3, 4 &1, 3 &2

There are 4 different combinations of getting a sum of 5.

The probability would be 4/36, which reduces to 1/9

Tell whether the given value is a solution of the inequality. a/6 > -4; a = -18

balandron [24]

First we simplify the inequality

1. multiply 6 by the other side of the inequality (-4)

Now we have ...

a > -24

Anything that can be a solution to the inequality must be greater than -24

-18 is greater than -24

This means that, YES! a = -18 IS a solution to the inequality
