Hello! You should select a, b, and c.
Think of it like on a number line, x could be 5, or -5 and still be the same distance from 0. Absolute vales are the same way, so if the answer is 5 or -5, its right! It cant be the last one because x, must only be 5 or -5. Hope that helps!
Answer:
13
1.57
Step-by-step explanation:
So we have two equations regarding the number of quarters <em>q</em> and the number of pennies <em>p:</em>
<em />
<em />
Which represents the total amount of coins and
Which represents the total amount of money in dollars.
So we are asked to evaluation each expression for the situation in which we have 6 quarters and 7 pennies. Thus, plug 6 in for <em>q</em> and 7 in for <em>p:</em>
<em />
<em />
This tells us that we have 16 coins in total.

This tells us that we have a total amount of $1.57.
<h2>Answer :</h2>
Let the number be x. Then according to the question,
Step 1 :- Adding 3
=> x + 3
Step 2 :- Multiply the sum by 2
=> 2×(x + 3)
Step 3 :- Subtract 6
=> 2(x +3) - 6
<h3>Thus the expression becomes 2(x +3) - 6. </h3>
Answer: (2,3)
