what is a factor for -20?​

Answers

Answer:

1 ,2,4,5,10,-1,-2,-4,-5,-10,20

Answer:

factors are 2 and 5.

Step-by-step explanation:

Factors are numbers which you can multiply together to get another number. For Example : The numbers 2 and 3 are factors of 6 because 2 x 3 = 6. A number can have many factors! Example : 2 and 4 are factors of 8, because 4 x 2 = 8. Also 1 and 8 can also be factors of 8, because 1 x 8 = 8.

on prime factorization, we get the factors of 20 as,

2 x 2 x 5 = 20.

Essentially, to factor a negative number, find all of its positive factors, then duplicate them and write a negative sign in front of the duplicates. For instance, the positive factors of −3 are 1 and 3.

-2 x 2 x 5 = -20

2 x 2 x -5 = -20

Under his cell phone plan, Noah pays a flat cost of $66.50 per month and $4 per gigabyte. He wants to keep his bill under $80 per month. Which inequality can be used to determine gg, the maximum number of gigabytes Noah can use while staying within his budget?

Answers

Answer: gg < 3.375

Step-by-step explanation:

From the question, we are informed that Noah pays a flat cost of $66.50 per month and $4 per gigabyte and that he wants to keep his bill under $80 per month.

The inequality that can be used to determine gg, the maximum number of gigabytes Noah can use while staying within his budget will be:

66.50 + 4gg < 80

4gg < 80 - 66.50

4gg < 13.50

gg < 13.50/4

gg < 3.375

After solving the equation, the value obtained for x is equal to 1.

What is an equation?

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given equation in the question,

13x - 12 = 7x - 6

13x - 7x = -6 + 12

6x = 6

x = 6/6

x = 1

Therefore, the value obtained for x will be equal to 1.

Answer:

x = 14, y = 37

Step-by-step explanation:

The angle vertical to (9x + 12 )° and 3x are same- side interior angles and are supplementary, sum to 180°, then

9x + 12 + 3x = 180

12x + 12 = 180 ( subtract 12 from both sides )

12x = 168 ( divide both sides by 12 )

x = 14, so

3x = 3 × 14 = 42

3x and 4y - 10 are adjacent angles and supplementary, then

3x + 4y - 10 = 180

42 + 4y - 10 = 180

4y + 32 = 180 ( subtract 32 from both sides )

4y = 148 ( divide both sides by 4 )

y = 37
