What are rational and irrational numbers and how are radicals related to rational exponents?

Answers

A rational numbers is any number that can be turned into a fraction/ratio. (Ex. 8, 0.75, 1/3). An irrational number is anything that can't be turned into a fraction/ratio. (Ex. Pi, square root of 2). Radicals and rational exponents are related because radicals can be converted into rational exponents.

Answer:

Any number that can be written as a fraction with integers is called a rational number. An irrational number is a number that cannot be expressed as a fraction for any integers. Radicals are related because for irrational numbers they cannot be simplified under the radical and you use a radical on the exponent to cancel it out, hope this helps!

Answers

Answer:

31

Method:

X + 21 = 52 is the same as 52 - 21 = x. 52 - 21 = 31 so x = 31

The equation is x + 21 = 52

In algebraic equations, you always want to isolate the variable (x) so To do that you would subtract 21 from both sides, and then you would do 52 - 21 = 32

x + 21 = 52
-21 = -21
x = 31

There is one third of a pie shared equally between 5 children. How much of the pie does each child receive? one ninth pie one fifteenth pie one eighteenth pie one twentieth pie

Answers

Answer:

Each of the 5 children receive one fifteenth pie

Step-by-step explanation:

Given:

One third of a pie shared equally between 5 children.

To find:

Amount of the pie with each of the 5 children.

Solution:

Number of children = 5

Also, one third of a pie shared equally between 5 children.

So,

Amount of the pie with each of the 5 children [tex]=\frac{\frac{1}{3} }{5}=[/tex] [tex]\frac{1}{15}[/tex]

Hence, each of the 5 children receive one fifteenth pie.

first we need to ask our self the question

Question: There is one third of a pie shared equally between 5 children. How much of the pie does each child receive?

__________________________________________________________

next we need to do the math. 1/3 divided by 5

i recommend turning the fractions into decimal points and then dividing them. after doing that we have the answer 0.067. but that is not a option. so turn it into a fraction! and we get 1/15.

Answer:

2x² - 8

Step-by-step explanation:

Given

(x - 2)(2x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

Solve the system.
4x + 3y = 10
9x - 4y= 1

Answers

it’s would be (1,2)

4x+3y=10 <— you solve for x and get x=5/2-3/4y

then substitute the value of x into 9x-4y=1 to get
9(5/2-3/4y)-4y=1

solve the equation for Y
y=2

now sub the value of y into x=5/2-3/4y
x=5/2 - 3/4 times 2

your answer would be x = 1

therefore you get (x,y) (1,2)

After solving the given equations, the value obtained for x and y will be equal to (1, 2).

What is an equation?

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given equations in the question,

4x + 3y = 10      (i)

9x - 4y = 1        (ii)

Multiply equation (i) by 9 and multiply equation (ii) by 4  

36x + 27y = 90

36x - 16y = 4

A similar term of x will cancel out from here.

y = 86/43

y = 2

Put y = 2 in equation (i)

4x + 3(2) = 10

4x = 4

x = 1
