A line segment has the endpoints (-7,-4) and (9,8). What are the coordinates of the
midpoint of this line segment?

Answer:

b=(3x² – 5x – 2)

l=(2x² + 12x - 4)

perimeter= 2(l+b)

=2( 2x² + 12x - 4+3x² – 5x – 2)

=2(5x²+7x-6)

=(10x²+14x-12) units

Answer: 21

Step-by-step explanation:

Answer:

w = -(5 u)/7

Step-by-step explanation:

Solve for w:

-w - 4 u = 6 w + u

Hint: | Isolate w to the left-hand side.

Subtract 6 w - 4 u from both sides:

-7 w = 5 u

Hint: | Solve for w.

Divide both sides by -7:

Answer: w = -(5 u)/7

Answer:

74, 138

Step-by-step explanation:

The numbers seem to be increasing by powers of 2. 14 - 12 = 2 = 2¹, 18 - 14 = 4 = 2², etc. Therefore, the next 2 numbers would be 42 + 2⁵ = 74 and 74 + 2⁶ = 138.

Answer:

x=22

Step-by-step explanation:

6x= 5x+22

6x-5x=22

x=22

Answer:

x = 22

Step-by-step explanation:

6x = 5x + 22

Subtract 5x from both sides.

x = 22

Answer: t>3

Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form: t>3

Interval Notation: (3,∞)

Step-by-step explanation:

Write the original inequality.     6t + 5 > 23

Subtract 5 from each side to undo addition.     6t > 18

Divide each side by 6 to undo multiplication.     t > 3

So our answer is t > 3.

Corinne do 4 pages homework in one hour.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

Corinne take 3 hours to do 12 pages of homework.

Since, We have;

Corinne take 3 hours to do 12 pages of homework.

Hence, In 1 hour, Number of pages = 12 / 3

Answer:

transportation fee= $20

Step-by-step explanation:

Giving the following information:

A canoe rental service charges a transportation fee and $8 an hour to rent a canoe. Mary and Joe rented a canoe for 6 hours, and the total cost was $68.

To calculate the transportation fee, first, we need to calculate the total rent cost for 6 hours.

Rent cost= 6*8= $48

Now, the transportation fee:

transportation fee= 68 - 48

transportation fee= $20

Answer:

Step-by-step explanation:

The sum of the measures of a linear pair of angles is 180°.

  (2x+24) +(4x+36) = 180

  6x = 120 . . . . . . subtract 60, collect terms

  x = 20

  (2(20) +24)° = 64° = ∠KPL

  (4(20) +36)° = 116° = ∠JPL

[tex]\huge\boxed{x=12}[/tex]

Step-by-step explanation:

If B is the midpoint of line AC, we know that lines AB and BC will be equivalent to each other.

Since we know the measures of AB and BC, we can just set these expressions equal to each other and find the value of [tex]x[/tex].

[tex]6x - 27 = 3(x+3)[/tex]

Let's simplify this equation until we have [tex]x[/tex] on one side of it.

Answer:

Step-by-step explanation:

Hey there!!!

According to the question,

Angle P is three less than twice less of an angle Q.

Then, let angle Q be x then angle P is 2x-3.

Now, it has also given that they are supplementary angle.

We know that the sum of supplementary angle is 180°.

Therefore, x+ 2x - 3°=180°.

Or, 3x = 180°-3°

Or, x = 177°/3

Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.

Hope it helps....

Let's set the sum of the angle measures equal to 540 degrees.

139 + 3x + 5x - 10 + 10x - 9 + 3x = 540

Let's combine like terms.

21x + 120 = 540

Subtract 120 from both sides.

21x = 420

Divide both sides by 21

x = 20

Answer:

x = 1/2

Step-by-step explanation:

Answer:

x = 0.5

Step-by-step explanation:

2(4x+2)=4x-12(x-1)   (by PEDMAS, we deal with the parentheses first by using the distributive property)

4x(2)+2(2)=4x+ x(-12) -1 (-12)

8x + 4 = 4x - 12x +12  (simplyfy each side)

8x + 4 = - 8x +12   (add 8x to both sides)

8x + 4 + 8x = 12

16x + 4 = 12    (subtract 4 from both sides)

16x = 12 - 4

16x = 8  (divide both sides by 16)

x = 8/16

x = 0.5

Answer:

[tex] \boxed{\sf n = 2m - 8} [/tex]

Step-by-step explanation:

Solve for n:

⇒2m - n = 8

Subtract 2 m from both sides:

⇒2m - 2m - n = 8 - 2m

2m - 2m = 0:

⇒-n = 8 - 2 m

Multiply both sides by -1:

⇒-n × (-1) = (8 - 2m) × (-1)

⇒n = 2m - 8

The required value of n is equal to n = 2m - 8.

An expression is given in the question ; i.e., 2m - n = 8.

We have to find the value of the 'n' .

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

As per the question ;

The given expression is 2m - n = 8.

Let's solve it to get the value of n.

The value of n can be find out , if we bring n to the left side of equal sign and 8 to the right of equal sign.

So ,

2m - n = 8 can be written as ;

2m = 8 + n

or

n = 2m - 8

Thus , the required value of n is equal to n = 2m - 8.
