If DE=23, EF=9, find the value of DF.

Answer:

5/6 and 75 1/3%

Step-by-step explanation:

8 1/3 = 25/3

25/3 pages of a book in 10 minutes

Multiply both numbers by the reciprocal of 10, which is 1/10

25/3 x 1/10 = 25/30 = 5/6

So, Charlotte reads 5/6 pages of a book in 1 minute.

Which is equal to 75 1/3%

Answer:

2.

Step-by-step explanation:

12 + (-16) + 24 - 18

= 36 - 34

= 2.

The value of the expression 12+(-16)+24-18 is 2, which can be computed using the commutative property.

The commutative property signifies that the order of terms in mathematical expressions does not matters. It applies only to addition and multiplication operations, and not to subtraction and division operations.

In the question, we are asked to evaluate: 12 + (-16) + 24 - 18.

By using the commutative property, we can write the expression

12 + (-16) + 24 - 18, as

= 12 + 24 + (-16) - 18

= 12 + 24 -16 - 18

= 36 - 34

= 2

∴ The value of the expression 12+(-16)+24-18 is 2, which can be computed using the commutative property.

Answer: Every 12 months (aka once a year)

=======================================================

Explanation:

List out the multiples of 4 and 3

Multiples of 4 = {4, 8, 12, 16, 20, 24, ...}

Multiples of 3 = {3, 6, 9, 12, 15, 18, 21, 24, ...}

The terms in bold are the common multiples between the two lists. The smallest or lowest common multiple (LCM) is 12. Every 12 months, or every 1 year, Tiki gets her hair cut and a new shirt in the same month.

-----------

A shortcut to find the LCM is to multiply the values 4*3 = 12. This only works when the GCF of the two original numbers is 1.

Step-by-step explanation:

The image point of A ( -7 , 4 ) after a translation of left by 3 units and up by 5 units is ( -10 , 9 )

What is Translation?

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the point be A ( x₁ , y₁ ) be = A ( -7 , 4 )

Now , the translation of point A ( -7 , 4 ) by left 3 units is

A ( -7 - 3 , 4 )

Now , the new point after the translation by left 3 units

A' ( -10 , 4 )

And the translation of point A' ( -10 , 4 ) by up 5 units is

A'' ( -10 , 4 + 5 )

Now , the new point after the translation up by 5 units is

A'' ( -10 , 9 )

So , the image after the translation of left by 3 units and up by 5 units is

A'' ( -10 , 9 )

Hence , the image after translation is is A ( -10 , 9 )

Answer:

Step-by-step explanation:

Answer:

answer is 2x+y = 20

Step-by-step explanation:

I did the test

The equation of a line with a slope of –2 that passes through the point (6, 8) will be 2x + y = 20.

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

The slope is -2. Then the equation of line will be

y = –2x + c

The line is passing through (6, 8), then we have

8 = –2(6) + c

8 = –12 + c

c = 8 + 12

c = 20

Then the equation of line will be

       y = –2x + 20

2x + y = 20

The equation of a line with a slope of –2 that passes through the point (6, 8) will be 2x + y = 20.

Answer:

Your number is 0.5, 2/4, or 1/2

Step-by-step explanation:

You need to set up your equation and then solve for x. We know that quadruple your number (x) plus 7 equals -5. Quadruple your number is the same as multiplying by 4. So it would be 4x + 7 = -5. We add seven to both sides and that would leave us with 4x = 2. Then we divide both sides by 4 to get x on it's own. x = 2/4 or 1/2
