A father's age is three times the sum
of the ages of his two children.After 5
years his age will be two times the sum
of their ages.Find the present age of the
father​

Answers

Answer 1
Let the age of father be x years and sum of the ages of his children by y years.
After 5 years,
Father's age = (x + 5) years
Sum of ages of his children = (y + 10) years
From the given information, we have:
x = 3y ...(1)
and x + 5 = 2(y + 10)
x - 2y = 15 ...(2)
From (1) and (2), we have,
3y - 2y = 15 y = 15
x = 3y = 45
Father's age = 45 years

steps for 540 + 6x = 810

Answers

Answer:

x = 45

Step-by-step explanation:

[tex]540 + 6x = 810[/tex]

Step 1 : Collect like terms

[tex]6x = 810 - 540[/tex]

Step 2 : Simplify

[tex]6x = 270[/tex]

Divide both sides of the equation by 6

[tex] \frac{6x}{6} = \frac{270}{6} [/tex]

Step 4 : Simplify

[tex]x = 45[/tex]

I hope it helps :)

Answer:

Well...X=45

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:540+6*x-(810)=0

Pull out like factors :-270 + 6x  =   6 • (x - 45)

Solve  :    x-45 = 0::

Add  45  to both sides of the equation:  x = 45

The number of people who attend a concert varies directly with the amount of money spent on advertising. If 790 tickets are sold when $2,547.75 is spent on advertising, how much money needs to be spent on advertisements to get a sellout crowd of 1500?

Answers

Answer:

$4837.5

Step-by-step explanation:

Given that,

790 tickets are sold when $2,547.75 is spent on advertising.

We need to find the money to be spent on advertisements to get a sellout crowd of 1500.

It is also mentioned that the number of people who attend a concert varies directly with the amount of money spent on advertising. Let money be x. So,

[tex]\dfrac{790}{2547.75}=\dfrac{1500}{x}\\\\x=\dfrac{2547.75\times 1500}{790}\\\\x=\$4837.5[/tex]

So, $4837.5 is spent on advertisements to get a sellout crowd of 1500

Find the slope of the line passing through each of the following pairs of po
(-6,0), (4,0)

Answers

Answer:

m = 0

Step-by-step explanation:

To find the slope of a line, use the equation:

m = y2 - y1 / x2 - x1

Then, substitute in numbers:

m = 0 - 0 / -6 - 4

m = 0 / -10

m = 0

Therefore, the slope of the line is 0, meaning it has zero slope.

The amount of money and dollars that it cost to purchase x square feet of the carpet is given by f(x)= 8x the insulation feet is $125 more than 8% of the cost of the carpet right function of g that represents the insulation fee then use the function to find the insulation fee for 175 square feet of carpet

Answers

Answer:

The insulation fee for 175 square feet of carpet is $237.

Step-by-step explanation:

The amount of money, f(x), that it cost to purchase x square feet of the carpet is:

f(x)= 8x

The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have

g(x)=8% of f(x)+125

[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]

[tex]\Rightarrow=0.64x+125[/tex]

The insulation fee for 175 square feet of carpet,

i.e for x=175

[tex]g(x=175)=0.64\times175+125=237[/tex]

Hence, the insulation fee for 175 square feet of carpet is $237.

What is an equation of the line that passes through the point (6,1) and is parallel to the line x + 3y = 15?​

Answers

Answer:

x + 3y - 9 = 0

Step-by-step explanation:

(d): x + 3y = 15 -> (d): x + 3y - 15 =0

if (d')║(d)

-> (d'): x + 3y + c = 0

but (d') passes through the point (6;1) => c = -x-3y = -6-3.1 = -9

=> (d'): x + 3y - 9 =0

The equation of the line that passes through the point (6,1) and is parallel to the line (x + 3y = 15) is 3y +x = 9 and this can be determined by using the one-point slope form of the line.

Given :

The line passes through the point (6,1) and is parallel to the line (x + 3y = 15).

The following steps can be used in order to determine the equation of the line that passes through the point (6,1) and is parallel to the line (x + 3y = 15):

Step 1 - Remember that when two lines are parallel then their slopes are equal.

Step 2 - So, the slope of the line that passes through the point (6,1) is -1/3.

Step 3 - So, using the one-point slope form of a line the equation of a line that passes through the point (6,1) and is parallel to the line (x + 3y = 15) can be determined.

Step 4 - The one-point slope form is given below:

[tex](y-y_1)=m(x-x_1)[/tex]

Step 5 - Substitute the values of the known terms in the above equation.

[tex](y-1)=-\dfrac{1}{3}(x-6)[/tex]

3y - 3 = -x + 6

3y +x = 9

Everything is rational but choice D

=======================================================

Explanation:

A rational number is anything in the form p/q where p and q are integers. The value of q cannot be zero.

So that's why -4/11 is rational. Here we have p = -4 and q = 11.

Any terminating decimal is rational. For choice A, we have 3.14 = 314/100

Choice C is also rational because [tex]\sqrt{\frac{4}{9}} = \frac{\sqrt{4}}{\sqrt{9}} = \frac{2}{3}[/tex]

Choice E is rational since 6 = 6/1.

In short, choices A, B, C, and E are rational.

------------------

The only irrational answer is d) 2pi

pi is irrational because we cannot write it as a fraction of two integers. Any number in the form n*pi, where n is any integer, is also irrational.

He has also estimated that he has already donated $23 to the foundation, Part if x represents the number of weeks thłt Darrell has been making a donation, write a recursive function to represent the total amount he has donated Explain your work​

Answers

Answerer: Darrell has already donated $23 to the foundation, so f (0) =$23.

Because x represents the number of weeks, and Darrell is contributing $1 every day, Monday through Friday, he will contribute a total of $5 per week. So, the total amount donated will increase by $5 each week. Therefore, the recursive function will be f (x) =f(x - 1) + $5, where f ($23).
