The simplification by combining like terms of 5v-3(2 -v)  is 8v - 6.

According to the given question.

We have an expression5v - 3(2 - v).

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression

5v - 3(2 - v).

Here 5v, and 3v both are the like terms.

So, we add coeffcients of v to simplify the given expression.

Therefore, the simplification of 5v -3 (2 -v ) is given by

5v - 3(2 - v)

= 5v - 6  + 3v

= 8v - 6

Hence, the simplification by combining like terms of 5v - 3(2 - v) is 8v - 6.

To express each fraction into its decimal we need to bring 100 at the denominator.

Fraction = numerator\denominator

For example :

1>    4\5

= 4*20\ 5* 20

      = 80\ 100

      = 0.80

2>   1\4

= 1 *20\ 4 *20

      = 20\ 100

       = 0.20

3>  49/50

= 49*2/50*2

= 98/100

=0.98

There are some numbers where it is not possible to make the denominator 100

Answer: C

Step-by-step explanation:

Since the inequalities for all 4 options are different, all you need to look at are the inequality signs.

For the line with a positive slope (bottom left to top right), the point it ends at is not filled in, so that point is not included meaning it is x > 1.

For the line with a negative slope (top left to bottom right), the point it ends at is filled in, so that point is included meaning it is x [tex]\leq[/tex] 1.

C. is the only one that has these inequalities.

The simplification of the given complex fraction 2/(x +y/3) is

6/(3x + y).

Accoring to the given question.

We have a complex fraction.

2/(x +y/3)

As we know that, complex fraction is a rational expression that has a fraction in its numerator, denominator or both.

For example:  (2/3)/(4/6)

So, the above complex fraction can be simplified by

(2/3) × (6/4)

= (2/3) ×  (3/2)

= 1

Thereofore, the siplification of the complex fraction 2/(x +y/3) is given by

[tex]\frac{2}{x + \frac{y}{3} }[/tex]

= [tex]\frac{2}{\frac{3x+y}{3} }[/tex]

= 2(3)/(3x + y)

= 6/(3x + y)

Hence, the simplification of the given complex fraction 2/(x +y/3) is

6/(3x + y).

Step-by-step explanation:

Answer: ∠L = 102°

               ∠N = 78°

Step-by-step explanation:

Quadrilaterals can be classified into Parallelograms, Squares, Rectangles, and Rhombuses. Square, Rectangle, and Rhombus are also Parallelograms.

A quadrilateral is called a parallelogram, if both pairs of its opposite sides are parallel. AB ∥ DC and AD ∥ BC. So, ABCD is a parallelogram. A parallelogram having all sides equal, is called a rhombus.

Given data,

In □KLMN, side LM ∥ side KN, side KL ≅ side NM If ∠K = 78°

then find the measure of ∠L, and ∠N                          

                           side LM∥ side KN

Interior angles on the same side of the transversal are supplementary.

                    ∠K + ∠L = 180°

                    78° + ∠L = 180°

                     ∠L = 180° -  78°

                      ∠L = 102°

Construction:

Draw LP ∥ MN

So, LM ∥ KN and LP ∥ MN

PLMN is a parallelogram

                   MN ≅ LP

Now MN  = LP and MN = KL

                     LP = KL

              ∠LKP = ∠LPK = 78°

LP ∥ MN so,

           ∠MNP =  ∠LPK = 78° (corresponding angles are equal)

                               ∠L = 102°

                               ∠N = 78°

Therefore,

                             ∠L = 102°

                               ∠N = 78°.

The length of an inscribed angle is half the length of the central angle. The circumscribed angle's measure is 180 degrees less the central angle's measure.

In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It is also the angle formed by two given points on a circle at a given point on the circle.

The length of an inscribed angle is half the length of the central angle. The circumscribed angle's measure is 180 degrees less the central angle's measure.

m ∠ABC =  m ∠ABD +  m ∠DBC  (∠ Addition Postulate)

m ∠ABD = 1/2 m(arc AD)    

m ∠DBC = 1/2 m(arc DC)  

(The measure of an inscribed ∠ whose side is diameter is half the measure of the intercepted arc (Case 1)).

m ∠ABC = 1/2 m(arc AD) + 1/2 m(arc DC) (Substitution)

m ∠ABC = 1/2 [m(arc AD) + m(arc DC)] (Factor)

m(arc AD) + m(arc DC) = m(arc AC) (Arc Addition Postulate)

When winter set in and the campaigning season came to a close, most Soldiers counted on a long, cold stay in a winter camp. The four log cabins at the center of the Army Heritage Trail represent the types of buildings which Soldiers in both the Union and the Confederate Armies spent the long dreary months of winter.

Given the task content, the cost, y, of any number of puppies, x is modeled by the equation y = mx + b where cost of any number of puppies is $12

There are three major types of equation. Namely,

An equation can be solved through the following methods:

Given:

6 puppies costs $172

10 puppies costs $220

y = mx + b

Where,

172 = m(6) + b

220 = m(10) + b

172 = 6m + b

220 = 10m + b

48 = 4m

m = 48/4

m = 12

172 = 6m + b

172 = 6(12) + b

172 = 72 + b

172 - 72 = b

100 = b

Therefore, the cost of any number of puppies is $12

The line created by 1st and 2nd is making the same angle with 3rd so all three will be colinear and 3rd is the midpoint of 1st and 2nd.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given the condition making a graph as shown below,

Now in ΔAOC and ΔBOC, the angle x is the same.

Distance AO = BO and CO is common side.

So both triangles will be congruent.

Since all corresponding side of two congruent triangles is the same.

So,

AC = BC hence C will be the midpoint of A and B.

Hence "The line created by 1st and 2nd is making the same angle with 3rd so all three will be colinear and 3rd is the midpoint of 1st and 2nd".

Answer:

Area = 792 m

Step-by-step explanation:

You can cut the polygon into 2 rectangles.
Subtracting 18 from 60 can give you the length of rectangle A, so 42 will be the new length for rectangle A.

Multiply 6 and 42 to get 252 for the area of rectangle A.

Multiply 18 and 30 to get 540 for the area of rectangle B.

(You multiply to find the area.)

Lastly you add both areas, 252 + 540, and the final result is:

Area = 792 m
