Answer:

No solution

Step-by-step explanation:

To isolate the variable, begin by adding 9x to each side

-6 - 9x = -9x - 4

-6 - 9x (+ 9x) = -9x (+ 9x) - 4

-6 ≠ -4

The equation in your answer has no solution. If you are supposed to find the value of x, you might want to double check for typos.

In the given particular sum we have to give reason why asolving 4 = 2x uses the division property of equality.

The reason for that why it is using division property of equality we wneed to know what is division property of equality : It states that when both side of the equation is divided by a real number other than 0 then the quotients remain same . It can be written as following : if a,b,c are real numbers where a = b , c ≠ 0 then ac = bc

for example suppose we have two breads of same size . We cut each of them into halfs and give it to  our friends , if we measure the remaining portions we will see that we are left with same portions of bread . Here at initial both the breads were same and we divide it by 2 and find that they are still same.

Solving 4 = 2x using the division property because in order to get the last portion that answer we have divide the both sides by 2 to get x by itself .

In the cuboid, the line segment parallel to AD is BC as they both lie on same plane and are directed in same direction.

Two lines are said to be parallel if they lie on the same plane and are directed towards the same direction.

Given in the question is a labelled cuboid.

From the definition of parallel lines, they should lie on the same plane. Therefore, we will eliminate EB and EH because they don't lie in the plane of AB. CD lies in the plane of AB, but is directed perpendicular to AB. BC is in the same plane in which AB lies and is also directed in the direction of AB.

Therefore, in the cuboid, the line segment parallel to AD is BC.

Step-by-step explanation:

Given line segment DEFG and lengths DF=12, EG=15, EF=4, you want the length DG.

The segment addition theorem tells you the whole is the sum of the parts.

  DF = DE +EF

  12 = DE + 4

  8 = DE . . . . . . subtract 4

And ...

  DG = DE +EG

  DG = 8 +15 = 23

The length DG is 23 units.

The percentage of people living on boat in Florida is 15.4%. The equivalent of this percentage to decimal is 0.154 and to fraction is 77/500.

55% live in a house, 25% live in an apartment, 4.6% in condo while the rest live on a boat. If all the percentages are summed up, they must be equal to 100%.

Let a% equals to the percentage of adult living on boat

55+25+4.6+a = 100

84.6 + a = 100

Collect like terms

a = 100 - 84.6

a = 15.4%

Therefore, the percentage of adult living on boat is 15.4%

To convert the percentage to decimal equivalence, one must divide it by 100%

15.4%/100%

= 15.4/100

= 0.154

To convert the percentage to fraction equivalence, one have to divide it by 100%

15.4%/100%

= 15.4/100

One has to make both the numerator and denominator of the fraction whole numbers, to do that one has to shift the decimal place behind the last digit, for a number without decimal point a 0 is added to the back of the number.

= 154/1000

Reducing the fraction to its lowest term, this is done by diving the numerator and denominator by a common factor

Given that

To find

So, according to the question

We have,

and the value of two angles m∠2 and m∠4.

From diagram we can see a is parallel to b and m is parallel to n.

So, we can say that

   m∠4 = m∠3    { they are vertical congruent angles } and

   m∠3 = m∠2    { they are congruent angles}

∴  m∠4 = m∠2 -------------(1)

Now, putting the values in equation(1)

So, will be get

                m∠4 = m∠2 -------------(1)

              11x+16 = x²+5x

  x²+5x - 11x-16 = 0

If the 6% sales tax had been computed on the sale price instead of on the regular price, the tax will be $0.04 lower.

It should be noted that from the information, Samwell bought a packet of pens and his receipt is shown above as $2.04.

Assume that sales tax is rounded to the nearest cent, If the 6% sales tax had been computed on the sale price instead of on the regular price, the difference will be:

Sales price = $1.89

Tax = $1.89 × 0.06 = $0.11

Therefore, the difference will be:

= Former tax amount - New tac amount

= $0.15 - 0.11

= $0.04

The midpoint between two points A(0,0) and B(8,4) is (4,2)

The distance between two points A(0,0) and B(8,4) is 4√5

To find the midpoint of two points,

We need to take an average of both the x and y components of both points

Two points A(x ₁,y₁) and B(x₂ ,y₂) are (0,0) and (8,4) respectively

Let M be the mid-point M(x, y),

x = x₁+x₂/2

 = 0+8/2

= 8/2

= 4

Similarly

y = y₁+y₂/2

  = 0+4/2

  = 4/2

  = 2

So, the midpoint of the two points A(0,0) and B(8,4) is (4,2)

To find the distance between two points,

We need to take the square root of the difference square of x and y, which is

d² = Δx² + Δy²

d = √(Δx²+Δy²)

Δx = x₂-x₁

    = 8-0

   = 8

Δy = y₂-y₁

    = 4-0

    = 4

Thus,

d = √(8²+4²)

d = √(64 + 16)  

d = √80

d = 4√5

So the distance between the two points is 4√5

We can use the distance equation to help us solve this question:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Plug in the given points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(8-(-4))^2+(-7-(-2))^2}\\d=\sqrt{(8+4)^2+(-7+2)^2}\\d=\sqrt{(12)^2+(-5)^2}\\d=\sqrt{144+25}\\d=\sqrt{169}\\d=13[/tex]

The length of line segment BC is 13 units.

Using the distance formula, the length of BC is: 13 units.

Given that:

B(8, -7) = (x1, y1)

C(-4,-2) = (x2, y2)

The distance formula that would be used to find BC is, d =[tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Thus, applying the distance formula, we have:

BC = √[(−4 − 8)² + (−2 − (−7))²]

BC = √[(−12)² + (5)²]

BC = √(144 + 25)

BC = √169

BC = 13 units

Therefore, using the distance formula, the length of BC is: 13 units.

Using ratio we can calculate that Mr. Singleton used approximately 1.33  pounds of sausage .

A ratio demonstrates how frequently one number is found within another. For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.

He uses 1 pound sausage for every 3/4 pound of cheese.

Ratio of sausage to cheese = 1 : 0.75 = 4 : 3 .

Now he uses 1 pound of cheese therefore let he uses x pounds of sausage.

Now using ratio:

x : 1 = 4 : 3

or , x / 1 = 4 / 3

or, x = 1.333..

or, x ≈ 1.33 pounds

Hence he uses 1.33 about pounds of sausage

The perimeter of the whole figure includes the sum of the side lengths and the value is -2 - 4m units

The area of a shape is the amount of space on the shape.

For most regular shapes, the area is the product of their width and the length

The area of this rectangle is given as

Area = 3m - 7m - 6

Evaluate the like terms

So, we have

Area = -4m - 6

The common factor of 4 and 6 is 2

So, we have the following equation

Area = 2(-2m - 3)

The area of the rectangle is

Area = Length * Width

So, we have

Length, L = 2

Width, W = -2m - 3

The perimeter of the rectangle is calculated as

P = 2 x (L + W)

So, we have

P = 2 x (2 - 2m - 3)

Evaluate the like terms in the above expression

So, we have

P = 2 x (-1 - 2m)
