Mathematics Middle School

why do we learn properties of real numbers?


answer quick :D

Answers

Answer 1

Answer:

The properties of the Real Number System will prove useful when working with equations, functions and formulas in Algebra, as they allow for the creation of equivalent expressions which will often aid in solving problems. In addition, they can be used to help explain or justify solutions.

Answer 2
Understanding the properties of real numbers will help us simplify numerical and algebraic expressions, solve equations, and more as you progress in studying algebra. In other words, the properties or axioms of real numbers are just one of many basic foundations of mathematics

Given the following expression.

2 1/4 - (-3 2/5)
A. Rewrite the expression using addition.

B. Evaluate the expression.

Answers

In order to rewrite the expression using addition, you would change all the subtraction signs and make the second terms negative. This means that your new expression is 2 + -2 1/4 + 3 2/5. If the number is already negative, the second negative sign would make it positive. Once you've got Part A done, do 2 + -2 1/4 which would give you -1/4. Then you add -1/4 and 3 2/5 by finding common denominators, 20. -5/20 + 3 8/20 would give you 3 3/20 as your final evaluated answer.

Simplify 18.03 – 3(12.7 + 8.06) ÷ 2.

Answers

Answer:

−13.11

Step-by-step explanation:

Simplify the expression.

− 13.11

Answer:

-13.11

Step-by-step explanation:

Remember: Please Excuse My Dear Aunt Sally (PEMDAS)

You use the parentheses first, so it is 18.03-3*(20.76)÷2

So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14

Then, you subtract from left to right, which gives you: -13.11

–7.5 • (–2¾) and explain how you got the answer

Answers

Answer:

20.625

Step-by-step explanation:

I turned 3/4 into a decimal which would be .75 and then multiplyed -7.5 times -2.75 and then when you multiply 2 negatives you get a positive and then 2.75 times 7.5 is 20.625

1. Negative • Negative = Positive

-7.5 • (-2 3/4) = Positive


2. Turn (-2 3/4) into an improper fraction: (- 11/4) to multiply:

-7.5 • (- 11/4) = 20.625

EXTRA: “If you want, you can turn -7.5 into a fraction too if it helps you better!”
