Answer 1

Answer: 1: 830

2: 30/448

3: 156

Explanation:

Answer 2

Answer & Step-by-step explanation:

#1. Insert the given values into the equation:

`16*14-4*6`

Use PEMDAS*. Simplify multiplication from left to right:

`224-24`

Simplify subtraction:

`200\\\\16a-4b=200`

#2. Insert the given values into the equation:

`(5*6)/(32*14)`

Use PEMDAS. Simplify multiplication:

`(30)/(448)`

Simplify division:

`(30)/(448)=(15)/(224) \\\\(5b)/(32a)=(15)/(224)`

#3. Insert given values into the equation:

`12(14)+(6-14-4)`

Use PEMDAS. Simplify parentheses:

`12*14+(-8-4)\\\\12*14+(-12)\\\\12*14-12`

Use PEMDAS. Simplify multiplication:

`168-12`

Simplify subtraction:

`156\\\\12a+(b-a-4)=156`

:Done

*PEMDAS:

Parentheses ()

Exponents x²

Multiplication and Division left to right × ÷

Addition and Subtraction left to right + -

It is important to use PEMDAS when working within grouping symbols like parentheses, too.
