Answer:

The example of deductive reasoning is:

All even numbers are divisible by 2. The number 18 is even, so it is divisible by 2.

Step-by-step explanation:

Deductive reasoning, also known as deductive logic, logical deduction is the process of reasoning from one or more statements to reach a logically certain conclusion.

Hence, the example of deductive reasoning is:

All even numbers are divisible by 2. The number 18 is even, so it is divisible by 2.

(

Since we are given a statement that:

All even numbers are divisible by 2.Also the number 18 is even

so, it's a certain or obvious conclusion that it is divisible by 2 )

( While in the first and second statement based on some or just one observation we can't judge that it would be true for everyone as it will not be a certain conclusion to draw for all)

Simplify the expression 10-4x(6+5-1) divided by 8+7
Eddi Din [679]
Simple,

writing out the problem...

\frac{10-4x(6+5-1)}{15}

Simplify it...

-4x(6+5-1)

-4x(11-1)

-4x(10)

-40x

Making it look like...

\frac{10-40x}{15}

Cancel out the common factors...

Thus making the answer:
