Why the commutative and associative properties don't hold true for subtraction and division

Answers

The commutative and associative properties do not apply to both subtraction and division because once you move around your variables, you will produce different results, whereas in addition and multiplication, any change in position of numbers won't affect the result. The identity properties apply to them because once you add, subtract, multiply, or divide a certain number from any other number, you produce the same result, or, in other words, keep the number's "identity".

Amanda and Katie are twins. At birth, Amanda was 6 3/10 pounds and Katie was 5 9/10 pounds. What is their combined birth weight?

Answer:

10 2/10

Step-by-step explanation:

because together it equals 9 12/10 but that cant happen so you add 1 to the 9 and get 10 so you have 2 left over

12.2 or 12 1/5

6 + 5 = 11
3/10 + 9/10 = 12/10
11 + 1 = 12 + 2/10
simplified is 1/5

12 1/5

Which of the following is NOT true? Question 19 options: (3x2y5)3=27x6y15 (1000x12y20z−3)0=1 52‾‾√3=523 42×43= 165

Answers

Answer:


Step-by-step explanation:

Lets try to simplify each to check which one is incorrect so it will be NOT true

first one is :

distribute the exponent so :

(3x^2y^5)^3 =3^3x^(2*3)y^(5*3)

27x^6y^(15)CORRECT

Second one is :

(1000x^(12)y^(20)z^(-30))^(0) =1

CORRECT because anything raised to exponent 0 is 1 .

Last one is :

4^2 *4^3 = 4^(2+3)\n=4^(6)\n=(4)^(2*3)\n=16^(3)

so Last is INCORRECT

Miguel's teacher asks him to color 4/8 of his grid. He must use 3 colors; red, blue, green. There must be more green sections than red sections. How can Miguel color the sections of his grid to follow all the rules?

Answers

One correct answer is:

2/8 green, 1/8 red, and 1/8 blue.

Explanation:

If there are 8 tiles, coloring 4/8 means coloring 4 tiles. Using those three colors, we could use each 1 time with 1 left over. Since we must have more green, we would use it twice; this would give us 2 green, 1 red and 1 blue.

Since the grid is not necessarily 8 squares, we must account for this by saying 2/8 green, 1/8 red and 1/8 blue.
1/8 red 1/8 blue 1/8 green and another 18 green 1/8+ 1/8+1/8+1/8=4/8

The Martin family's truck gets an average of 25 miles per gallon. Predict how many milrs they can drive using 7 gallons of gas.

Answers

If the Martin family's truck gets an average of 25 miles per gallon. The distance they can drive using 7 gallons of gas will be 175 miles.

What are arithmetic operations?

The study of numbers and their operations, which are relevant to all other fields of mathematics, is part of the discipline of arithmetic operations. Addition, subtraction, multiplication, and division are the basic operations that make up this system.

It is given that, the Martin family's truck gets an average of 25 miles per gallon.


We have to find the number of miles they can drive using 7 gallons of gas.

We'll apply division by Splitting into equalhalves or groups, the division may be used to decide how to distribute fuel evenly among a group.


The distance they can drive for the 7 gallons of gas will be,

=25 miles per gallon × 7 gallons

=175 miles

Thus, if the Martin family's truck gets an average of 25 miles per gallon. The distance they can drive using 7 gallons of gas will be 175 miles.

Okay so on average if they can go 25 miles per gallon that would mean you could just multiply 25 and 7 to get 175. So on average they could go 175 miles on 7 gallons of gas. Keep in mind that the answer can and will change depending on traffic, how fast or slow they are going, and if they are traveling behind a big-rig that moves more air that would normally be putting pressure on the car to push out of the way  but the big-rig helps save gas but it can also waste more gas if they are driving slower then normal.
Sorry for the extra information once I start it's hard to stop. Any way I hope this helps.
