Two number cubes are rolled. What is the probability that the sum of the numbers rolled is either a 7 or an 11?

If you can, answer at least 2 question I put 10 points on it

igomit [66]

Answer:

a) one solution(x = 9)

b) no solution

c) infinite solutions

Step-by-step explanation:

a) To solve this equation, we can add 4 on both sides in order to isolate x:

x - 4 =5

+ 4 + 4

x = 9

Since x equals 9, that counts as only one solution, as there is only one value of x that makes the equation true.

b) We start by subtracting 2x from both sides to combine the variable terms:

2x - 6 = 2x + 5

-2x -2x

-6 = 5

The statement, -6 = 5 is never true and it is not dependent on the value of x. This means there are no solutions to this equation.

c) We can start by subtracting 3x from both sides to combine the terms with x:

3x + 12 = 3x + 12

-3x -3x

12 = 12

The statement above is always true, and no matter the value of x, it will always be true. This means there are infinite solutions to the equation.

I’m completely lost can anybody help solve this

Marizza181 [45]

Answer:

$\huge\boxed{x=54^o}$

Step-by-step explanation:

<em>Look at the picture.</em>

<em />

We have:

$l=108^o$

Therefore

$2\alpha=108^o$ <em>divide both sides by 2</em>

$\dfrac{2\alpha}{2}=\dfrac{108^o}{2}\\\\\alpha=54^o$

In Exercises 8-10, sketch the figure described.

Lunna [17]

The sketch answers to question 8, 9 and 10 is given in the image attached.

<h3>What is an intersecting lines?</h3>

A link is known to be intersecting if two or more lines are said to have cross one another in a given plane.

Note that the intersecting lines are known to be one that often share a common point, and it is one that can be seen on all the intersecting lines, and it is known to be the point of intersection.

Looking at the image attached, you can see how plane A and line c intersecting at all points on line c and also GM and GH and line CD and plane X as they are not intersecting

Therefore, The sketch answers to question 8, 9 and 10 is given in the image attached.
