What is a factor of 10

Answers

The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10.

Describe any errors. Then solve the equation correctly

Answers

Answer:

I can't see what the student did to solve the equation so I'll just solve the equation step by step here.

Step-by-step explanation:

2(x-7)=x-9

2x-14=x-9 Use distributive property to solve the parenthesis

x-14=-9 Subtract the x on both sides

x=5

Answer:

See step by step

Step-by-step explanation:

He didnt use the distributive property.

How to solve it is

[tex]2(x - 7) = x - 9[/tex]

[tex]2x - 14 = x - 9[/tex]

[tex]x - 14 = - 9[/tex]

[tex]x = 5[/tex]

HELP! 50 POINTS! 75 if I chose your answer as the best! easy!

Answers

Step-by-step explanation:

Question 1:

In the expression 4y - 6x² + 5 + 9x, there are

4 terms. (4y/6x²/5/9x) A term consists of a coefficient and a variable, or otherwise a constant term like 5.

Question 2:

4(6x - 5) - 7x

= (24x - 20) - 7x

= 17x - 20.

Therefore the correct answers are

the 1st and 2nd options.

Question 3:

3x - 8y + 11x - 4 + 5y

= (3x + 11x) + (5y - 8y) - 4

= 14x - 3y - 4.

The 4th option is correct.

Question 1

There are 4 terms.

They are 4y, 6x^2, 5, and 9x.

Terms are separated by operation signs (+, -, ×, ÷).

Even if a constant is multiplied by a variable, if there isn't a multiplication sign, it's one single term.

Question 2

Use the distributive property. Multiply the term outside the variable by the terms inside.

4×6x = 24x

4×(-5)=-20 (there's a negative sign incase you don't see it)

24x-20-7x

Since 24x and 7x are like terms, you can subtract them.

24x-7x=17x

17x-20

You can see the first and second choices are correct.

Question 3

Combine the like terms.

The like terms are

3x and 11x

-8y and 5y

-4

Add them all.

3x+11x=14x

-8y+5y=-3y

-4

So the expression simplified is...

14x-3y-4

It's the third choice.

PLZ answer fast urgant help needed!

Answers

Answer:

0.5041 = 50.41% probability of getting 2 of the same colour

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

What is the probability of getting 2 of the same colour?

Both blue or both red

Since they are replaced, we have, in each trial:

6 blue from a set of 6 + 5 = 11

5 red from a set of 6 + 5 = 11

Probability of both blue:

Each with 6/11 probability. So

[tex]P = (\frac{6}{11})^2 = \frac{36}{121}[/tex]

Probability of both red:

Each with 5/11 probability. So

[tex]P = (\frac{5}{11})^2 = \frac{25}{121}[/tex]

Total:

[tex]p = \frac{36}{121} + \frac{25}{121} = \frac{61}{121} = 0.5041[/tex]

0.5041 = 50.41% probability of getting 2 of the same colour

since r = 4, you make the equation :

g=25-3(4)

first you multiply 3 and 4 and you get 12

g=25-12
