Answer:

5/2 is rational

Step-by-step explanation:

rational numbers either end and don't repeat or they repeat the same numbers like 0.359 or 0.333333333333333...

5/2 = 2.5 and it just ends with no repeating

5/2 is rational

Answer:

x = 1

y = -3/2

Step-by-step explanation:

Step 1: Arrange the equations with like terms in column.

Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.

Step 3: Solve for x.

4x-2y=7

3x+2y=0

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

7x = 7

x = 1

Step 4: Substitute the value of x and solve for y.

4(1)-2y=7

4-2y=7

-2y=7-4

-2y=3

y=-3/2

Answer: 11

Answer:

Support your answer with an example. ▫ The opposite of an opposite of a number is the original number. The opposite of the opposite of negative 6 is negative 6 because the opposite of 6 is 6. The opposite of 6 is 6

Answer: You're right. You've figured it out correctly!

Answer:

at least 81 times. playing 80 times would mean you played exactly what it's worth, 7*80=560, so playing 81 times means you pocket a difference of 7 dollars. if you're going to be playing at least 81 times yearly, go for the membership..

Answer:

14 & 15

Step-by-step explanation:

The area of the square is given by the equation: [tex]A = s^2[/tex] so therefore the length of the side is: [tex]s = \sqrt{A}[/tex].

So we take [tex]s = \sqrt{200} = 14.14[/tex]

And this is between the integers 14 and 15.

Step by Step explanation:

Rather than eating hot cheetos and facetiming your friends such as hi*za and reb***a you should study! Studying is the key to success rather than gossip and other stuff. The answer is wisdom, nothing less and nothing more. Go on the right path to success not the wrong way. Oh and, I ain't never seen two pretty best friends, it's always one of them that gotta be ugly.

7n^2 + 5 = 453

Subtract 5 from both sides:

7n^2 = 448

Divide both sides by 7:

N^2 = 64

Take the square root of both sides:

N = 8

[tex]\sf Length\:=\:(x+7) \\\\\sf

Breadth\:=\:(x+3) \\\\\sf

Area= Length\: x\: Breadth \\\\\sf

=(x+3)(x+7) \\\\\sf

=x^2+7x+3x+21 \\\\\sf

\boxed{Area=x^2+10x+21} \\\\ \\\\\sf

Now, \:Perimeter\:=\: 2x(length +breadth) \\\\\sf

\boxed{Perimeter=4x+20} [/tex]

[tex]l = (x + 3) \\ b = (x + 7)[/tex]

Area:

[tex] = l \times b \\ = (x + 3)(x + 7) \\ = x(x + 7) + 3(x + 7) \\ = {x}^{2} + 7x + 3x + 21 \\ = {x}^{2} + 10x + 21[/tex]

Perimeter:

[tex] = 2(l + b) \\ = 2((x + 3) + (x + 7)) \\ = 2(x + 3 + x + 7) \\ = 2(2x + 10) \\ = 4x + 20[/tex]

Give me a question to answer

Answer:

a=q+f

Step-by-step explanation:

1. a-f=q

2. you need to do the opposite of -f which is +f to cancel it out

after that you need to do the +f to the q

Hope this helps

Using the literal equation a-f = q, the solution for a = p + q

A literal equation are  type of equations which have two or more unknown variables . A literal equation can be solved by adding or subtracting or multiplying or divide by same numbers to the both sides of the equation in order to solve the expression for the required variable.

For example if an given equation is x+ y =2 and we want to solve it for y

Then we will try to keep y on one side and take remaining terms to other side.⇒ y = x-2  is solution for y.

Given equation :

a- f = q

To solve for a, add f to both sides

⇒ a- f +  f = q+ f

⇒ a = q + f

Solution for a is q +f.

Step-by-step explanation:

Multiply the coordinates by 7.

Answer:

(4 x + 9) (16 x^2 - 36 x + 81)

Step-by-step explanation:

Factor the following:

64 x^3 + 729

64 x^3 + 729 = (4 x)^3 + 9^3:

(4 x)^3 + 9^3

Factor the sum of two cubes. (4 x)^3 + 9^3 = (4 x + 9) ((4 x)^2 - (4 x) 9 + 9^2):

(4 x + 9) ((4 x)^2 - 4 9 x + 9^2)

4×9 = 36:

(4 x + 9) ((4 x)^2 - 36 x + 9^2)

Multiply each exponent in 4 x by 2:

(4 x + 9) (4^2 x^2 - 36 x + 9^2)

4^2 = 16:

(4 x + 9) (16 x^2 - 36 x + 9^2)

9^2 = 81:

Answer: (4 x + 9) (16 x^2 - 36 x + 81)

Answer:

(4x+9)(16x2−36x+81)

Step-by-step explanation:

Factor 64x3+729

64x3+729

=(4x+9)(16x2−36x+81)
