Answers

Answer:

[tex]x=-35[/tex]

Step-by-step explanation:

Given the following question:

[tex]59+x=24[/tex]

To find the answer we are going to use inverse of operations to isolate the variable, doing this we can then find the value of the variable.

[tex]59+x=24[/tex]
[tex]59-59=0[/tex]
[tex]24-59=-35[/tex]
[tex]x=-35[/tex]

Your answer is "x = -35."

System of Linear Equations

System of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.

For solving this equation, firstly, rewrite the information given:

                                          [tex]\frac{p-5}{q-5}=\frac{9}{1} \;(1)\\ \\\frac{p+20}{q+20}=\frac{7}{3} \;(2)[/tex]

From equation 1, you have:

                                        [tex]p-5=9q-45\\ \\ p=9q-40[/tex]

And from equation 2, you have:

                                  [tex]3*(p+20)=7*(q+20)\\ \\ 3p+60=7q+140\\ \\[/tex]

Now, substitute p=9q-40 in 3p+60=7q+140

                                 [tex]3p+60=7q+140\\ \\3*(9q-40)=7q+140\\ \\ 27q-120=7q+140\\ \\ 20q=20\\ \\ q=10[/tex]

If q=10 for p=9q-40,  you will have:

                                [tex]p=9q-40\\ \\ p=9*10-40\\ \\ p=90-40\\ \\ p=50[/tex]

Therefore, the ratio  [tex]\frac{p}{9}[/tex]  is equal to [tex]\frac{50}{9}[/tex].

Using the future value formula, it is found that $546,148,903,191,724.25 will be in Devon's account.

What is the future value formula?

It is given by:

[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]

In which:

P is the payment.n is the number of payments.r is the interest rate.

In this problem, the parameters are as follows: P = 587, r = 0.0525, n = 40 x 12 = 480.

Hence:

[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]

[tex]V(480) = 587\left[\frac{(1 + 0.0525)^{480-1}}{0.0525}\right][/tex]

a 12. A bicycle wheel has a radius of 40 cm. How many times does it revolve during a journey of 10 km? Give your answer to the nearest 100. [For T, use either your calculator value or 3.142.​

Answers

The bicycle wheel revolving is a illustration of circumference

The bicycle wheel revolves 4000 times

How to determine the number of times?

The given parameters are:

Radius (r) = 40 cm

Distance =10 km

Start by calculating the circumference of the wheel

[tex]C =2\pi r[/tex]

This gives

[tex]C =2 * 3.142 * 40[/tex]

[tex]C =251.36[/tex]

The number of times to cover a distance of 10 km is then calculated as:

[tex]n =\frac{10km}{251.36cm}[/tex]

Evaluate the quotient

[tex]n =3978.35773[/tex]

Approximate

[tex]n =4000[/tex]

Hence, the bicycle wheel revolves 4000 times

Find the equation of the line which passes through (-2,1) and which is perpendicular
to the line 2x - 4y = -8. State the answer in slope-intercept form and graph.
-

Answers

A line that is perpendicular to a line with slope m has slope -1/m which is the opposite reciprocal of the original slope.

In this case the original line in standard form is

2x-4y=-8

transform this into slop intercept form

-4y=-2x-8

4y=2x+8

y=(1/2)x+2

The slope of this original line is 1/2 therefore the perpendicular line will have slope -2

y'=2x'+b

then substitute in the order pair (x',y')

1=2(-2)+b

b=5

Therefore equation of line is

y=2x+5

The graph is just following this equation!
