Rational numbers are numbers that can be written as a fraction. Rational numbers include the integer set. These numbers can be written as repeating and terminating decimals also.

Irrational numbers are the numbers that can not be turned in to a fraction. These are decimals that are non-terminating and non-repeating.

A rational number is any number that can be represented as a fraction. (7=7/1 or 52 = 26/1 ).
An irrational number is a number like 3.14159 (pi) or anything like that.

Find the first four terms for the arithmetic sequence given a1 = 6 and d = 5

DENIUS [597]

Answer:

6, 11, 16, 21

Step-by-step explanation:

To obtain the first 4 terms add the common difference 5 to the previous term, that is

a₁ = 6

a₂ = a₁ + 5 = 6 + 5 = 11

a₃ = a₂ + 5 = 11 + 5 = 16

a₄ = a₃ + 5 = 16 + 5 = 21

Three numbers have absolute values of 2,4 and 9. The product of all the numbers is positive.

Margaret [11]

The absolute value of a number is how far away it is from 0 on a number line.
Example) 2 is two numbers away from 0, but neg. 2 (-2) is also two numbers away from 0

So basically. A positive number has the absolute value of itself. (2= a value of 2) and negative numbers have the absolute value of the positive form of that number. (-9= a value of 9)

Numbers that have the absolute value of 2: 2 and -2
Numbers that have the absolute value of 4: 4 and -4
Numbers that have the absolute value of 9: 9 and -9

You are looking to add your numbers together to make a positive.

So the answer is the positive answers to the absolute values: 2,4,9

2+4+9=15

15 is a positive number.

mojhsa [17]

Answer: The price of item is $495.

Step-by-step explanation:

Since we have given that

Amount that Sara have = $90

Amount that Rachel have = $405

If they combine their money they will have enough to buy item.

So, Price of item would be

Amount that Sara have + Amount that Rachel have

$=90+405\\\\=\$ 495$

Hence, the price of item is $495.
