Find three equivalent fractions for 2/3 by multiplying by 3/3, 5/5 and 6/6. What property of multiplication do we use to find equivalent fractions?

Answers

The property of multiplication used to find equivalent fractions is called the multiplicative identity. It says that when a number is multiplied by 1, it remains same. When finding equivalent fractions, the numerator and denominator of a fraction is multiplied by the same number. In other words, the fraction is multiplied by 1, hence it remains the same.

The equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

2/3 by multiplying by 3/3, 5/5, and 6/6.

= (2/3)(3/3)

= 6/9

= (2/3)(5/5)

= 10/15

= (2/3)(6/6)

= 12/18

The multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

The numerator and denominator of a fraction are multiplied by the same number for determining equivalent fractions.

Thus, the equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

5 = -2( x– 1)

5= -2x+2

Answers

5 = -2 (x – 1) (remove the parantheses)

5 = -2x + 2 (move the terms)

2x = 2 - 5 (calculate)

2x = -3 (divide both sides)

x= -3/2

5= -2x + 2 (move the terms)

2x = 2 - 5 (calculate)

2x = -3 (divide both sides)

x= -3/2

Answer:

A, B, and D

Step-by-step explanation:

A would be a correct answer since the book was 94 pages shorter than expected, so it was -94 pages of what was expected.

B would be a correct answer since Andrew no longer has that $94. His account would show a transaction of -$94.

C would not be a correct answer since the temperature was a positive number. For it to have been a correct answer, the temperature would've had to have been -94.

D would be a correct answer since Jennifer no longer has 94 apples. She now has a value of -94 apples compared to the value she had before she started selling them.

Answers

Given :

The Dobson exit is halfway between the Mt. Airy exit and the Elkin exit. If the Elkin exit is located at (-5,-2) and the Dobson exit is located at (-1,4).

To Find :

How far is it from the Elkin exit to the Mt. Airy exit.

Solution :

E(-5,-2) , D(-1 ,4 ) .

It is also given that Dobson exit is halfway between the Mt. Airy exit and the Elkin exit.

Let , location of Elkin exit is A(h,k) .

So , point D in terms of A and E is given by :

[tex](\dfrac{h-5}{2},\dfrac{k-2}{2})[/tex] .

Comparing it with given D :

[tex]\dfrac{h-5}{2}=-1\\\\h=3[/tex] [tex]\dfrac{k-2}{2}=4\\\\k=10[/tex]

Therefore , the location of Mt. Airy exit is ( 3, 10 ) .

Distance between Elkin exit to the Mt. Airy exit.

[tex]D=\sqrt{(5-3)^2+(-2-10)^2}\\\\D=12.17\ units[/tex]

Therefore , distance between Elkin exit to the Mt. Airy exit is 12.17 units .

Hence ,this is the required solution .

When reaching mile marker 4 on the trail, Susan uses her GPS to find that her current elevation is 6135 feet. If she follows the trail until its end at mile marker 9, her elevation will be 8290 feet. What is the average change in elevation of Susan's position from mile marker 4 to mile marker 9, in feet per mile marker?

Answers

Answer:

Change in elevation= 431 feet/mile marker

Step-by-step explanation:

given data

Elevation at mile marker 4 = 6135 feet

Elevation at mile marker9 = 8290 feet

to find out

average change in elevation

solution

we get here average change in feet per mile marker that is express as

average change in feet per mile = change in elevation ÷ change in mile marker .....................1

put hree value we get

average change in feet per mile = [tex]\frac{8290-6135}{9-4}[/tex]

average change in feet per mile = 431 feet/mile marker

Change in elevation= 431 feet/mile marker

What IS the solution to 1−(13q−5)=−6

Answers

Answer:

q = 12/13

Step-by-step explanation:

Step 1: Write equation

1 - (13q - 5) = -6

Step 2: Solve for q

Distribute -1: 1 - 13q + 5 = -6

Combine like terms: 6 - 13q = -6

Subtract 6 on both sides: -13q = -12

Divide both sides by -13: q = 12/13

2n/5=10, what is the value of 2n-1

Answers

Answer:

Step-by-step explanation:

First, multiply 5 on both sides:

2n = 50

Then, we divide 2 on both sides:

n = 25

Now we got the value of n, let's calculate 2n - 1.

First, multiply 2 by n so we can get 2n:

2 * 25 = 50

Then, we calculate 50 - 1:

We got 49, and that's the answer ^^

Hope this helps!

The value of 2n-1 is 49 if 2n/5=10, after applying the concept of a linear equation and the value of n is 25.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

2n/5 = 10

2n = 50

n = 25

Plug the value of n in the expression 2n - 1

= 2(25) - 1

= 49

Thus, the value of 2n-1 is 49.
