[tex]\rightarrow \sf \dfrac{x^{-4}y^{-8}}{x^{12}y^{-12}}[/tex]

Answer:

x+4<12

Step-by-step explanation:

You did not put the inequalities, but that is how the statement would look like. "And" is a clue that we're adding. So, x + 4 would be the first part, and we know when the open part of this symbol '</>' is pointed at a number then that number is greater than the number before it. So, in this case, you'll want to have that symbol pointed at 12 because x + 4 is less than 12.

Hey there!

=> 59 + x = 24

=> x = 24 - 59

=> x = -35

Therefore, 59 + (-35) = 24

Answer:

[tex]\boxed{\sf{x=-35}}[/tex]

Step-by-step explanation:

A subtraction property of equations is the subject of this problem.

For the correct answer, you need to isolate x from one side of the equation.

59+x=24

First, switch sides.

x+59=24

Then, subtract by 59 from both sides.

[tex]\sf{x+59-59=24-59}[/tex]

Solve.

[tex]\sf{24-59=-35}[/tex]

[tex]\boxed{\sf{x=-35}}[/tex]

Therefore, the solution is x=-35, which is our answer.

Step-by-step explanation:

all you really need to do is find the common denominator and it'll get you an answer for the numerator.

Answer:

13/15

Step-by-step explanation:

You first need to find the common denominator between both 3 and 5, so you have to find the number that would be the best, which is 15. Then you have to multiply the numerator by how many times you went up for that number, for 2/3 would be times 5, and 1/5 would be times 3. Doing this will get you your answer, 13/15.

Answer:

2/3

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

6/9 can be simplified into 2/3 by dividing both the numerator and the denominator by the greatest common factor, 3.

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

It is given by:

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

In which:

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]

[tex]V(480) = 546,148,903,191,724.25[/tex]

The bicycle wheel revolving is a illustration of circumference

The bicycle wheel revolves 4000 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

The ratio p:9 is equal to 50:9 = [tex]\frac{50}{9}[/tex].

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].

Answer:

20 cm

Step-by-step explanation:

A2 + B2 = C2

 C is your hypotenuses = 29 cm

And one leg of a right triangle is 21 cm long

So we have A2 = (21cm)2 = 441 cm + B2 = (29cm)2 = 841cm

B2 = 841 - 441 = 400

 B = √400 = 20

So the third leg of a triangle that has a hypotenuses of 29 cm and one side of a right triangle that is 21 cm long is 20 cm
