5.6 as an improper fraction simplified?
Phoenix [80]
As a fraction, it would be 5 6/10. Then you multiply the denominator by the whole number 5x10 and add the numerator. So,
10X5+6=56
56/10
divide by 2
28/5 is the simplified version

Which expression is equivalent to 4 (3n - 5)?
mart [117]

Expression 4 (3n - 5) is equivalent to <em><u>C: 12n - 20</u></em>

<h3>Further explanation </h3>

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

  • 1. phrases

algebraic forms separated by arithmetic operations

consists of one phrase (monomial) to many phrases (polynomial)

  • 2. variable

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

  • 3. constants

is a fixed value, can be a number

  • 4. arithmetic operations  ⇒ +, - , : , x

Calculation operations include multiply, divide, add, substract, etc.

There are several properties in integer multiplication operations

  • 1. closed property

Multiplication between integers will produce integers too

  • 2. commutative property

a x b = b x a

  • 3. associative property

ax (bxc) = (axb) xc

  • 4. identity

ax1 = 1 x a = a

  • 5. distributive  property

*<em> addition </em>

ax (b + c) = axb + axc

* <em>substraction </em>

ax (b-c) = axb - axc

We can use distributive  property  of <em>substraction   </em>to solve the problem

\displaystyle =4(3n-5)\\\\=4x3n - 4x5\\\\=12n-20

"Equivalent to" means having the same value.

From the answer choices , which produce the same expression is C. 12n-20
