How do you know that dividing by 1/6 is the same as multiplying by 6?

Answer:

C, D, F

Step-by-step explanation:

She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.

That means she walked 12 miles plus 1/4 of 12 miles.

She walked

12 + 1/4 * 12

You can factor out 12 from the expression above, and write it as

12(1 + 1/4)

Now you can do the addition in parentheses.

12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)

Answer:

C, D, F

Answer:

12 + 1/4 x 12, 12 x 5/4, and 12 (1 + 1/4)

Step-by-step explanation:

To solve this, you need to add 1/4 of 12 to 12. 1/4 of 12 is 3, and 12 + 3 is 15. All of these equations are equal to 15, therefore they are all correct.

1/4 x 12 = 3 + 12 = 15

12 x 5/4 = 60/4 = 15

1 + 1/4 = 5/4

5/4 x 12 = 60/4 = 15

Step-by-step explanation:

The angles are vertical because they are opposite to each other

75 = 4x -25 vertical angles

100 = 4x

x= 25° Algebra

Answer:

X = 25 degrees

Definitions:

Vertical: Opposite angles/angles that share a common side.

Adjacent: Congruent meaning same measure.

Step-by-step explanation:

This equation would be vertical because they are opposite from eachother:

Our equation would look like this:

75 = 4x - 25

Then add 75 and 25 to get 100:

75 + 25 = 100

Now our equation would look like this:

100 = 4x

Lastly, divide 100 with 4:

100 ÷ 4 = 100

Side note: 25 x 4 = 100

Your answer would be x = 25 degrees.

Answer:

x= −1 /2 y+4

Step-by-step explanation:

Let's solve for x.

2x+y=2(6−2)

Step 1: Add -y to both sides.

2x+y+−y=8+−y

2x=−y+8

Step 2: Divide both sides by 2.

2x /2= −y+8 /2 x= −1 /2 y+4

Step-by-step explanation:

For finding we go from

Back to front that is,

First,

Sum of a number and 5 that is = n + 5

Then,

Twice of their sum that is = 2(n+5)

Hence,

Option C that is 2(n+5) (Ans)

Answer:

In order to be considered a language, a system of communication must have vocabulary, grammar, syntax, and people who use and understand it. Mathematics meets this definition of a language. Linguists who don't consider math a language cite its use as a written rather than spoken form of communication

Answer:

Below in bold.

Step-by-step explanation:

The total sum of the numbers in A is 124 and the sum of the numbers in B = 56

Let x be the number passed from A to B, then from the given information:

124 - x = 56 + x + 20

124 - 56 - 20 = 2x

48 = 2x

x = 24.

a) So the number passed is 24.

b) Sum of numbers in B = 56 + 24 = 80.

c) Let pencil cost x then pen will cost 1.1 - x.

Now the pen costs 1 pound more than the pencil

so  1.1 - x - x = 1

-2x = -0.1

x = 0.05.

So the pen costs 1.1 - 0.05 = £1.05.

Answer:

6x+7y

Step-by-step explanation: hope I helped

Answer:

( a ) 3a ( 4 ) b

= 12ab

( b )Let's simplify step-by-step.

5x + 9y + x − 2y

= 5x + 9y + x + − 2y

Combine Like Terms:

= 5x + 9y + x + −2y

= ( 5x + x ) + ( 9y + −2y )

= 6x + 7y
