Answer:

x = (k+10)/6

Step-by-step explanation:

k = 2(3x - 5)

Distribute the 2

k = 6x - 10

Add 10 to each side

k+10 = 6x-10+10

k+10 = 6x

Divide each side by 6

(k+10)/6 = 6x/6

(k+10)/6 = x

Answer:

x = (k + 10) / 6

Step-by-step explanation:

k = 2(3x - 5)

k = 6x - 10

k + 10 = 6x

(k + 10) / 6 = x

Answer:

24

Step-by-step explanation:

let x be the number of children in the class , then

number of boys = [tex]\frac{1}{4}[/tex] x , so

x = [tex]\frac{1}{4}[/tex] x + 18 ( multiply through by 4 to clear the fraction )

4x = x + 72 ( subtract x from both sides )

3x = 72 ( divide both sides by 3 )

x = 24

There are 24 children in the class

The amount of material needed by Marta to make the flag is;

[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] square inch.

The total cost of making the flag is;

[tex]\rm 0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] dollar.

Given

Marta is making a flag with the given dimensions.

The perimeter of the flag is 100 inches.

Let us consider that the flag has a triangular shape.

According to the Hero's formula;

The area of the triangle is given by;

[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where, s is the semi perimeter and a, b, and c are the sides of the triangle.

Semi perimeter s = P/2,

Since the perimeter of the flag is 100 inches.

[tex]\rm S=\dfrac{100}{2}\\\\S=50[/tex]

The dimensions of triangular shape are [tex]\rm d_1, d_2 \ and \ d_3[/tex].

Then,

The area of the triangular flag becomes;

[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]

So the amount of material needed to make the flag is;

[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]

Therefore,

The cost of material = C = $0.15 per square inch

So the total cost in making the flag will be;

[tex]\rm C\times A=0.15 \times A\\\\=0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].

Hence, The amount of material needed by Marta to make the flag is [tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].

Answer: her present age is 4

Step-by-step explanation:

Proof: 4+12=16

Square root 4 is 16

Answer:

  4

Step-by-step explanation:

Let x represent her present age. The given relation is ...

  x +12 = x^2

Putting this in standard form, we can factor it:

  x^2 -x -12 = 0

  (x -4)(x +3) = 0

Solutions to this quadratic are x = 4, x = -3. The -3 solution is extraneous in this context.

Answer:

y = 4[tex]\sqrt{3}[/tex]

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

y² = product of the segments on the hypotenuse of the large right triangle.

y² = 4 × 16 = 48 ( take square root of both sides )

y = [tex]\sqrt{48}[/tex] = [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]

Answer:

Step-by-step explanation:

●Using the identity :-

●(a+b) (a-b) = a^2 - b^2

●Here, a = 6p and b = 5

=> (6p+5) (6p-5)

=> (6p)^2 - (5)^2

=> 36p^2 - 25

Answer:

Given, x,y and 40 are the angles of a triangle.

Therefore, x+y+40=180

x+y=140

The difference between the two angles x and y is 30.

Therefore, x−y=30 ....(2)

Add equations (1) and (2), we get

2x=170

⇒x=85

Substitute this value n equation (2), we get

85−y=30

⇒y=85-30

⇒y=55

Therefore, angles of a triangle are x=85, y=55 and 40.

Answer:

Step-by-step explanation:

for x :

180° - 40° = 140°  

40° / 2 = 20°

x = 20°

for y :

20° + 90° = 110°

180° - 110° = 70°

x = 70°

Answer:

If Lucas reaches into the refrigerator to get a yogurt without looking, there is a 3/5 probability that Lucas will choose a raspberry yogurt.

There is a 3/5 probability that he will choose a red apple if it is the first item he selects.

There is a 9/25 probability that Lucas will eat a raspberry yogurt and a red apple.

Step-by-step explanation:

3/5 x 3/5 = 9/25

Answer:

Step-by-step explanation:

Total of 5 yogurts: 3 raspberry + 1 vanilla + 1 peach

Probability of yogurt being raspberry = 3/5 = 0.6

Total of 5 apples: 2 green + 3 red

Total number of snacks = 10

Probability of choosing a red apple = 3/10 = 0.3

Probability of raspberry yogurt AND red apple = 0.6 x 0.3 = 9/50 = 0.18

The statements that are true regarding the diagram given are:

The triangle sum theorem states that all the three interior angles in a triangle have a sum of 180 degrees all together.

Thus, in the diagram given, the statements that are all true are:

m∠3 + m∠4 = 180° (angles on a straight line)

m∠4 = m∠1 + m∠2 (external angle theorem)

m∠1 + m∠2 + m∠3 = 180° (triangle sum theorem).

Answer:

Step-by-step explanation:

We see that:

For any x₁ and x₂ ∈ N,

It it confirmed one-to-one, hence it is injective

Check the surjectivity:

f(x) = y ∈ N

Let y = 2, then:

Since x is not natural, the function is not surjective

Answer:

This function is injective only.

Step-by-step explanation:

N = natural numbers = positive whole numbers equal to or greater than 1.

Therefore [tex]N \rightarrow N[/tex] means that both the input and output are natural numbers.

A function is surjective if for every element in the codomain, there is at least one element in the domain.

Therefore, this function is NOT surjective.  For example, there is no natural number for x for which f(x) = 2.

A function is injective if for every element in the codomain, there is at most one element in the domain.  This is also called "One-to-One".

Therefore, this function IS injective as there is either none or only one value of x for each value in the codomain.
