Solve the equation x-4/2=10

Answer:

The cost of one unit of electricity is $0.185

Step-by-step explanation:

Amount charged = $120.99

Units of electricity used = 654

The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.

So that,

cost of one unit of electricity = [tex]\frac{120.99}{654}[/tex]

                                    = 0.185

cost of one unit of electricity = $0.185

This implies that the cost of electricity used is charged at $0.185 per unit.

Thus for 654 units of electricity used, the cost would be;

654 x $0.185 = $120.99

Answer:

The two lines are coincident (essentially the same line) so every point on the line is a solution. Normally you would say they have infinitely many solutions.

An example of this would be:

y = 2x + 3

2y = 4x + 6

The statement that matches this situation would be D.

Answer:

D. The system of equations does not have only one solution (it has infinitely many) because the lines do not intersect at *only* one point.

Answer:

Selling price of each cap = £6.75 (Approx.)

Step-by-step explanation:

Given:

Number of caps = 500

Cost of caps = Rs. 200,000

Export tax = 5%

Profit = 150%

£ 1 = Rs. 155.63

Find:

Selling price of each cap

Computation:

Cost of 1 cap = 200,000 / 500

Cost of 1 cap = Rs 400

After Add export tax = 400 + 400(5%)

After Add export tax = Rs 420

After profit = 420 + 420(150%)

After profit = Rs 1050

Selling price of each cap = 1,050 / 155.63

Selling price of each cap = £6.75 (Approx.)

We conclude that

[tex]3x-11>7x+9\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<-5\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-5\right)\end{bmatrix}[/tex]

Please check the attached diagram which shows the solution on the number line.

Step-by-step explanation:

Given the inequality

[tex]3x-11>7x+9[/tex]

Add 11 to both sides

[tex]3x-11+11>7x+9+11[/tex]

Simplify

[tex]3x>7x+20[/tex]

Subtract 7 from both sides

[tex]3x-7x>7x+20-7x[/tex]

Simplify

[tex]-4x>20[/tex]

Multiply both sides by -1 (reverses the inequality)

[tex]\left(-4x\right)\left(-1\right)<20\left(-1\right)[/tex]

Simplify

[tex]4x<-20[/tex]

Divide both sides by 4

[tex]\frac{4x}{4}<\frac{-20}{4}[/tex]

Simplify

[tex]x<-5[/tex]

Therefore, we conclude that

[tex]3x-11>7x+9\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<-5\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-5\right)\end{bmatrix}[/tex]

Answer:

53.33% probability he calls a person from school.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

What is P(call a person from school)?

He has 30 total contacts, of which 16 are from school. So

[tex]P = \frac{16}{30} = 0.5333[/tex]

53.33% probability he calls a person from school.

Answer:

Perimeter = 5x - 2

Step-by-step explanation:

Perimeter of the figure = sum of all its side lengths

Thus:

Perimeter = (x - 4) + (x + 3) + (x - 2) + x + (x + 1)

Perimeter = x - 4 + x + 3 + x - 2 + x + x + 1

Collect like terms

Perimeter = x + x + x + x + x - 4 + 3 - 2 + 1

Perimeter = 5x - 2

Answer:

x = 120/29

Step-by-step explanation:

-1/6(x + 18) + 1/5(x + 5) = x - 6

-1/6x - 3 + 1/5x + 1 = x - 6

-1/6x + 1/5x + 1 - 3 = x - 6

-1/6x + 1/5x - 2 = x - 6

-5/30 + 6/30x = x - 6 + 2

1/30x = x - 4

1/30x - x = -4

-29/30x = -4

-29/30x • 30/29 = -4 • 30/29

-x = -4/1 • 30/29

-x = -120/29

-x/-1 = 120/29/-1

x = 120/29

Step-by-step explanation:

Answer:

B) 4x + 8y = 2(2x + 4y)

C) 4x + 8y = 4(x + 2y)

D) 4x + 8y + 12z = 4(x + 2y + 3z)

E) 5x + 10y = 5(x + 2y)

Step-by-step explanation:

We would assume a value for the variables a, b, c, x, y and z.

Let x, a = 1

Let y, b = 2

Let z, c = 3

A) a + b + c = 3abc

When a = 1, b = 2 and c = 3

Substituting into the above equation, we have;

1 + 2 + 3 = 3(1*2*3)

6 ≠ 3(6)

6 ≠ 18 (not equivalent)

B) 4x + 8y = 2(2x + 4y)

When x = 1 and y = 2

Substituting into the above equation, we have;

4(1) + 8(2) = 2(2*1 + 4*2)

4 + 16 = 2(2 + 8)

20 = 2(10)

20 = 20 (equivalent expression)

C) 4x + 8y = 4(x + 2y)

When x = 1 and y = 2

Substituting into the above equation, we have;

4(1) + 8(2) = 4(1 + 2*2)

4 + 16 = 4(1 + 4)

20 = 4(5)

20 = 20 (equivalent expression).

D) 4x + 8y + 12z = 4(x + 2y + 3z)

When x = 1, y = 2 and z = 3

Substituting into the above equation, we have;

4(1) + 8(2) + 12(3) = 4(1 + 2*2 + 3*3)

4 + 16 + 36 = 4(1 + 4 + 9)

56 = 4(14)

56 = 56 (equivalent expression).

E) 5x + 10y = 5(x + 2y)

When x = 1 and y = 2

Substituting into the above equation, we have;

5(1) + 10(2) = 5(1 + 2*2)

5 + 20 = 5(1 + 4)

25 = 5(5)

25 = 25 (equivalent expression).

Step-by-step explanation:

x- intercept is the x coordinate when y is 0

4x + 7(0) = 6

4x = 6

x = 1.5

(1.5, 0)

y- intercept is when x is 0

4(0) + 7y = 6

7y = 6

y = 6/7

( 0, 6/7)

Answer:

Let's define:

C = number of children tickets bought

A = number of adult tickets bought.

We know that "On a certain day,  if 14 times as many children's tickets were bought as adult meal tickets"

Then we have:

C = 14*A

And we also know that:

"the total revenue  from selling all tickets was $2,584"

Then:

C*$4 + A*$9 = $2,584

Then we have a system of equations:

C = 14*A

C*$4 + A*$9 = $2,584

The first step to solve these is to isolate one of the variables in one of the equations, and then replacing it in the other equation. We can already see that C is already isolated in the first equation, then we can just replace it in the second one to get:

(14*A)*$4 + A*$9 = $2,584

A*$56 + A*$9 = $2,584

A*$65 = $2,584

A = $2,584/$65 = 39.75

Here we should have a whole number, (So one of the numbers given may be incorrect) This is because we can not have a 0.75 of a ticket sold.

In this case, we know that:

C = A*14

C = 39.75*14 = 546.5

We could round this up to get a whole number; 547

About 547 children tickets were sold.

Answer:a

Step-by-step explanation:

The function h(x) is increasing on the interval (5, ∞).

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

The function h(x) = |x − 5| + 2 is increasing on an interval where the derivative is positive.

If x < 5, then h(x) = -(x-5) + 2 = 7-x, and if x > 5, then h(x) = x - 5 + 2 = x - 3. Thus,

h'(x) =[tex]\left \{ {{ -1, for x < 5} \atop { 1, for x > 5}} \right.[/tex]

Since h'(x) is positive for all x > 5, the function h(x) is increasing on the interval (5, ∞).
