Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x

Answer:

(10x+1)°=(12x-5)°. [vertically opposite angle]

1+5=12x-10x

6= 2x

3=x

therefore,x=3

You roll a dice three times what is the probability that you roll an even number on the first roll, and odd on the second roll a

<h3>Answer:</h3>

D. 1/24

<h3>Step-by-step explanation:</h3>

Assuming the die is fair and the events are independent, the probability of the series of events is the product of the probabilities of the individual events.

p(even) = 3/6 = 1/2

p(odd) = 3/6 = 1/2

p(5) = 1/6

Then the joint probability is ...

.. (1/2)·(1/2)·(1/6) = 1/24

Answer:

$x=27$

Step-by-step explanation:

we know that

$(3x+9)^o+90^o=180^o$ ----> by supplementary angles (form a linear pair)

Solve for x

Combine like terms

$(3x+99)^o=180^o$

subtract 99 both sides

$3x=180-99\\3x=81$

Divide by 3 both sides

$x=27$

Answer:

A, x>3

Step-by-step explanation:

You solve the equation as normal by crossing out both sides and getting what equals to x, but since you divided by a negative the sign flips and you are left with your answer. Hope this helps!
