The first step in solving the equation is adding like terms. once you do that you get x+2=5.

Answer: Step 1: Combine 2/3x and 1/3x to get x or 1x

x+2=5

Step 2: Subtract 2 from both sides.

 x=5−2

Step 3: Subtract 2 from 5 to get 3.

x=3

You roll a standard number cube. Find P(number is not 3).

yan [13]

Answer[:]
C) 5/6

You roll a standard cube. You want to find P, and P is NOT rolling the number 3. Rolling the number 3 would be a 1/6 chance because that is 1 outcome of 6 chances. The probability of not rolling a three would be 5/6. It's a higher probability, as well.

Hi, I'm happy to help!

Parallel means that two lines are lined up in the same directions and will never intersect even if they were extended forever in directions.

Let's look at the first option of AB, and AD. We can see that both lines intersect at point A, so AB and AD are not parallel.

For the next option of CD and BE, we can see that both lines don't intersect and won't ever even if the lines were extended. So, CD and BE are parallel.

For the third option, we have BC and DE. These lines don't intersect and aren't in line to ever do so. Therefore, BC and DE and parallel.

The last option is AD and BC. These two lines will never meet, but, they aren't line up in the same directions. AD is traveling upwards while BC isn't. Think about being able to make a road out of the two lines, it would never work. AD and BC are not parallel.

To sum it up: You should select the 2nd and 3rd options because those lines are parallel.

I hope this was helpful, keep learning! :D

65. If the diameter of the sphere is halved, what will be the difference in volume?

Murrr4er [49]

Answer:

Hi there !

A. 1/8 of the original volume
24 is the mode

<h2>Step-by-step explanation:</h2>

<h3>Question 1 :-</h3>

LET RADIUS OF SPHERE= R

VOLUME OF SPHERE= $( \frac{4}{3})\pi \: {r}^{3}$

WHEN RADIUS IS HALVED RADIUS IF SPHERE=R/2

VOLUME= $( \frac{4}{3} )\pi( \frac{r}{2})^{3}$ = {(4/3)πR^3}/8

THE VOLUME WILL BECOME 1/8 TH OF THE ORIGINAL VOLUME.

<h2>Question 2 :-</h2>

Wehave,

Mode+2×Mean=3×Median

⇒Mode=3×Median−2×Mean

Given : Mean=21 and Median=22

Putting the given values, we get

Mode=3×22−2×21=66−42=24.

Hope it helps u....

Stay safe, stay healthy and blessed

Have a great day !

Thank you

11. Isaac wrote two simplified expressions that were not equal to each other. Each equation also had

Elodia [21]

Answer:

The equation has only one solution

Step-by-step explanation:

* Lets explain how to solve the problem

- There are three types of solutions for the equations

Case (1)

# Two sides of the equation have different coefficient of the variable

and same or different numerical terms, then the equation has only

one solution

- Ex: 2x + 5 = x + 5, lets solve it

∵ 2x + 5 = x + 5

- subtract x from both sides

∴ x + 5 = 5

- Subtract 5 from both sides

∴ x = 0

- Zero is a solution

∴ The solution of the equation is x = 0

- If the numerical terms are different x will be any other value, so the

equation has only one solution

∴ The equation has one solution

Case (2)

# Two sides of the equation have same coefficient of the variable,

and different numerical terms, then the equation has no solution

- Ex: 14x - 20 = 14x + 10, lets solve it

∵ 14x - 20 = 14x + 10

- Subtract 14x from both sides

∴ - 20 = 10

- The left hand side not equal the right hand side , then there is

no value of x can make the two sides equal

∴ The equation has no solution

Case (3)

# Two sides of the equation have same coefficient of the variable,

and same numerical terms, then the equation has infinitely

many solutions

- Ex: 3x + 5 = 3x + 5, lets solve it

∵ 3x + 5 = 3x + 5

- Subtract 3x from both sides

∴ 5 = 5

- The left hand side is equal to the right hand side , then x can be

any value because the two sides is already equal without x

∴ The equation has infinitely many solutions

∵ He will write two expressions simplified , not equal , have different

coefficients on the variables and equate them, then it is like

the first case

- That means not same coefficient of the variable, and may be not

same numerical term

∴ The equation has only one solution
