For this case we must propose an algebraic expression associated with:
"four times a difference of a number and seven is 12"
So we have to:
Four times a difference of a number and seven is represented as:
So we have the expression is:
We apply distributive property to the terms within parentheses:
We add 28 to both sides:
We divide between 4 on both sides:
Answer:
The B option is correct.
<h2>Exponent</h2>Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.
Given
A number is -906,060.
<h3>To find </h3>The equivalent number of the given number.
<h3>How to find the equivalent number of the given number?</h3>We know the number is -906,060.
It can be represented as .
Thus, the B option is correct.
