2. Write a word phrase for the algebraic expression. 3x - 7

A. The difference of three times a number x and seven.

B. The difference of seven and three times a number x.

C. Three times a number x fewer than seven. ☺

D. The quotient of three times a number x and seven.

6. Name the subset(s) of real numbers to which the number ZERO belongs. Select all that apply.

A. Irrational Numbers
B. Integers ☺
C. Whole Numbers ☺
D. Natural Numbers

Thanks!

Anybody there?

2.

no, 3x-7 is 7 less than 3 times a number. You have given us 7-3x

(A)

6. correct

thx

2. To write a word phrase for the algebraic expression 3x - 7, you can break it down into two parts: 3x and -7.

- The term 3x means three times a number x. So, you can say "three times a number x."
- The term -7 represents a decrease or subtraction. So, you can say "fewer than seven."

Putting it together, the word phrase for 3x - 7 is "Three times a number x fewer than seven."

Answer: C. Three times a number x fewer than seven. ☺

6. To determine the subset(s) of real numbers that the number zero belongs to, let's examine the options:
- Irrational Numbers: Irrational numbers are numbers that cannot be written as a fraction or ratio. Since zero can be expressed as 0/1, it is a rational number. Therefore, zero does not belong to the subset of irrational numbers.
- Integers: Integers include whole numbers and their negatives. Since zero is neither positive nor negative, it is considered an integer.
- Whole Numbers: Whole numbers include zero and all positive integers. Therefore, zero is a whole number.
- Natural Numbers: Natural numbers include positive integers greater than zero. Since zero is not positive, it is not considered a natural number.

Based on the definitions above, the subsets to which the number zero belongs are:

Answer: B. Integers ☺
C. Whole Numbers ☺
