What is an easy method to solve for x in a basic algebra problem? Example: 3x + 5x + 8x = 32

Answers

Answer:

2

Step-by-step explanation:

3x + 5x  + 8x = 32

taking x common,

(3 + 5 + 8)x = 32

16x = 32

x = 32 / 16

x = 2

Answer: See below

Explanation:

The ultimate method of solving algebra problems will be trying any operations to isolate x, which then gives the value of x.

Operations include combining like terms, dividing and multiplying terms, and etc.

I would be solving [3x + 5x + 8x = 32] as an example.

Solve:

Given

3x + 5x + 8x = 32

Combine like terms through addition

8x + 8x = 32

16x = 32

Divide 16 on both sides to isolate x

16x / 16 = 32 / 16

If D is the midpoint of AB and AB = 15, what is AD?
7.5
15
22.5
30

Answers

Answer:

If AB=15 and D is the midpoint that means AD=DB which is half of AD,

AD=AB/2

AD=15/2

therefore AD=7.5

In a three digit number, the tens digit is thrice the unit digit and hundred’s digit is
twice the unit digit. If the sum of all three digits is 12. Find the number.

Answers

Answer:

x = 4, y = 6, z = 2

Explanation:

Let x, y and z represent the 3 digit.

Where:
x = 2z
y = 3z
z = z

And: x + y + z = 12

2z + 3z + z = 12
6z = 12
z = 2

If z = 2 then:

x = 2(2) = 4
y = 3(2) = 6

Point Q is on line segment PR
. Given QR=2x+4,PQ=x, and PR=4x-10, determine the numerical length of PR.

Answers

Answer:

46

Step-by-step explanation:

PR = PQ + QR

4x - 10 = x +  2x + 4   {Combine like terms}

4x - 10 = 3x + 4     {Add 10 to both sides}

4x        = 3x + 4 + 10

        4x = 3x + 14              {Subtract 3x from both sides}

4x - 3x  = 14

          x = 14

PR = 4x - 10    {Plugin x = 14}

     = 4*14 - 10

     =  56 - 10

     =  46

The freshman class is planning a picnic. The cost of a permit to use the park is
$250. To pay for the permit, there is a fee of $.75 for each freshman and $1.25 for
each guest who is not a freshman. Two hundred freshman plan to attend. How many
guests must attend in order to at least pay for the permit? Let g represent the number
of guest attending.

Answers

Answer:

80

Step-by-step explanation:

Permit : $250
Fee for freshies : $0.75
Fee for non-freshies: 1.25

If you have 200 freshman coming , you would multiply 0.75 X 200= $150

Now how many non-freshies need to show up to meet the $250 permit?

250(permit) - 150= $100

$100 divided by $1.25 = 80 non-freshies would need to show up , enabling to pay the full of the $250 permit fee

How many packages of invitations and how many packages of envelopes did Ronnie buy? Enter your answers in the boxes. packages of invitations packages of envelopes

Answers

Answer:

5---6

Step-by-step explanation:

Given, the package of invitations contain [tex]12[/tex] invitations and package of envelopes contain [tex]10[/tex] envelopes.

Let [tex]x[/tex] and [tex]y[/tex] denote the number of invitation packages bought by Ronnie respectively.

It is given that, Ronnie bought the fewest number of invitations and envelopes so that there is exactly one envelope per invitation with none left over.

That is,[tex]12x-10y=0[/tex].

When, [tex]x=1[/tex] the value of [tex]y[/tex] becomes [tex]1.2[/tex].

It is not possible, since the number package cannot be in decimals.

When, [tex]x=2[/tex] the value of [tex]y[/tex] becomes [tex]2.4[/tex].

This is not possible, since the number package cannot be in decimals.

When, [tex]x=3[/tex] the value of [tex]y[/tex] becomes [tex]3.6[/tex].

This is not possible, since the number package cannot be in decimals.

When, [tex]x=4[/tex] the value of [tex]y[/tex] becomes [tex]4.8[/tex].

This is not possible, since the number package cannot be in decimals.

When, [tex]x=5[/tex] the value of [tex]y[/tex] becomes [tex]6[/tex].

This is not possible, since the number package cannot be in decimals.

Thus, Ronnie bought [tex]5[/tex] packages invitations and [tex]6[/tex] packages envelopes so that there is exactly one envelope per invitation with none left over.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If two triangles are congruent, then the ratio of the corresponding sides will be ONE.

The line DE is the perpendicular bisector of AC. Then we have

In triangles ΔABD and ΔCBD,

DB = DB (Common side)

∠ABD = ∠CBD = 90°

AB = BC (Bisector length)

This hyperbola is centered at the origin. Find its equation. Foci: (-9,0) and (9,0) Vertices: (-2,0) and (2,0)

Answers

Answer:

Step-by-step explanation:

focus distance=9

a=2 f²=a²+b² ==> b²=9²-2²=77 ==> b=√77

[tex]\dfrac{(x-0)^2}{2^2}- \dfrac{(y-0)^2}{77}=1\\\\\\\boxed{\dfrac{x^2}{4}- \dfrac{y^2}{77}=1}\\[/tex]

Equation of hyperbola is  [tex]\frac{x^{2} }{4} -\frac{y^{2} }{77} =1[/tex].

What is hyperbola?

Hyperbola is defined as an open curve having two branches which are mirror images to each other.

A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant : a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.

Given

Foci: (-9, 0) and (9, 0)

Foci: (±9, 0)

Vertices: (-2,0) and (2,0)

Vertices: (±2, 0)

So, a = ±2, c = ±9

Now [tex]c^{2} =a^{2} +b^{2}[/tex]

[tex]b^{2} =c^{2} -a^{2}[/tex]

[tex]b^{2} =9^{2} -2^{2}[/tex]

[tex]b^{2} =81-4[/tex]

[tex]b^{2} =77[/tex]

Equation of hyperbola is

[tex]\frac{x^{2} }{a^{2} } -\frac{y^{2} }{b^{2} } =1[/tex]

⇒ [tex]\frac{x^{2} }{4} -\frac{y^{2} }{77} =1[/tex]

Hence, equation of hyperbola is  [tex]\frac{x^{2} }{4} -\frac{y^{2} }{77} =1[/tex].

Answer is B, there are two equal base angles in an isosceles triangle, so given that ( 75+75 =150), the total of the interior angles in any triangle is 180, so 180-150 =30 ( which is the vertex angle) , the upper angle of the triangle.
