Answer:

3x4=12 is the same as

4x3=12 and

12/3=4 and

12/4=3

The commutative property of multiplication is true for the expression 4 x 3 = 3 x 4 = 12.

Multiplication is one of four mathematical arithmetic operations.

It is also a process of adding the same types of expression for some number of times.

The repeated addition is multiplication.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

The commutative property of multiplication:

Let a and b are the two numbers.

And the product of a x b is n.

So,  a x b = b x a = n

Changing the numbers position does not affect the result.

Here,

3 x 4 = 4 x 3

12 = 12

This expression holds the commutative property of multiplication.

Therefore, 3 x 4 = 12 holds the commutative property.

Additional comment

Both the numerator and denominator are polynomial functions. A polynomial function is odd if it contains only odd-degree terms, like the function in the numerator. A polynomial function is even if it contains only even-degree terms, like the function in the denominator. (A constant is 0 degree--even.)

A rational function consisting of the ratio of odd or even functions (not "neither"), will be odd or even according to the parity of the ratio:

  odd/odd = even/even = even function

  odd/even = even/odd = odd function . . . . . the situation in this problem

Answer:

y=2.50+175*(x-1)

$4727.50

Step-by-step explanation:

y=2.50+175*(x-1)

The first km costs 2.50 which is why you add it. You do x-1 because the 175 is charged for each additional km. So, if you traveled one km it would cost 2.50.

y=2.5+175*(28-1)

y=2.5+175*27

y=2.5+4725

y=$4727.50

Fruits:         Vegetables:

50                          42

Step-by-step explanation:

According to the diagram we can get the ratio of fruits to vegetables is 5:7

1) Fruits: 30,Let's suppose the amount of veegtables is x so, 30:x=5:7⇒5x=30*7⇒x=42

2) Vegetables: 70, lets suppose the amount of fruits is y

So, y:70 = 5:7 ⇒ 7y = 70 * 5 ⇒ y = 50{ use the ratio }

Monkey      Fruits        Vegetables

A                  30              42

B                  50             70

There was 4 boys and 11 girls in the class.

Let x represent the number of boys and y represent the number of girls.

Since the number of girls in the class was 1 less than 3 times the number of boys, hence:

y = 3x - 1

3x - y = 1         (1)

Also, there were 15 students in all, hence:

x + y = 15        (2)

Solving equations 1 and 2 simultaneously gives:

x = 4, y = 11

Hence, there was 4 boys and 11 girls in the class.

Answer:

[tex]\frac{8}{15}[/tex] of a mile

Step-by-step explanation:

To find a segment of a fraction, you must first find the LCM of each value's denominator:

LCM - Lowest Common Multiple

The lowest common multiple is the number that shows up first in each number's multiple set.

Example: LCM of 4 and 6

Multiples of 4: 4, 8, 12, 16, 20

Multiples of 6: 6, 12, 18, 24, 30

Because 12 is the first number to show up in each multiple set, 12 is the LCM.

So, to be able to solve this problem easy, do the same with 5 and 3:

5, 10, 15, 20, 25

3, 6, 9, 12, 15

Since 15 is the first number in both sets, 15 is the LCM.

The next step is to multiply [tex]\frac{4}{5}[/tex] by [tex]\frac{x}{x}[/tex], x being the value that can be multiplied with the denominator to equal 15:

[tex]\frac{4}{5}[/tex] × [tex]\frac{3}{3}[/tex] = [tex]\frac{12}{15}[/tex]

To find how much [tex]\frac{2}{3}[/tex] of [tex]\frac{12}{15}[/tex] is, multiply the fractions together:

[tex]\frac{12}{15}[/tex] × [tex]\frac{2}{3}[/tex] = [tex]\frac{24}{45}[/tex]          

Simplify the fraction by dividing the numerator and denominator by 3.

[tex]\frac{24}{45}[/tex] ÷ [tex]\frac{3}{3}[/tex] = [tex]\frac{8}{15}[/tex]

Because the fraction can't be simplified any further, Aimee has walked a total of [tex]\frac{8}{15}[/tex] of a mile.

Answer:

24 years old

Step-by-step explanation:

Given information:

• Alvin is 11 years older than Ella.

• The sum of Alvin and Ella's ages is 59.

First, put the given information into an equation that can solve for Ella's age:

x = Ella's age

x + 11 = Alvin's age

x + x + 11 = 59        Combine like terms.

2x + 11 = 59            Subtract both sides of the equation by 11 to isolate x.

2x = 48                   Divide both sides by 2 to get the value of x.

x = 24

Ella's age is 24 years old.

Train 1 = x + 6.4

Train 2 = x

(x) + (x + 6.4) = 717.6

2x + 6.4 = 717.6

2x = 711.2

x = 355.6

Train 1 = 355.6 + 6.4 = 362 mph

Train 2 = 355.6 mph

Where's the question? I think you forgot to post it.

Answer:

19 keyboards

Step-by-step explanation:

Let d = thumb drives; and k = computer keyboards

Total number of sales of thumb drives and keyboards is 50

50 = d + k

Rearranged:

d = 50 - k

Total revenue from the sale of $24 thumb drives and $49 keyboards is $1675

1675 = 24d + 49k

Sub in d = 50 - k

1675 = 24(50 - k) + 49k

1675 = 1200 - 24k + 49k

475 = 25k

k = 475/25

k = 19

(To check, d = 50 - 19 = 31)
