Scientific notation is usually written in powers of tens, in this case:
-1.5 + 7.5
factor out -1.5, divide 7.5 by 1.5 to factor it out of it as well (7.5 divided by -1.5) and make sure you get NEGATIVE 5.
-1.5(1 x -5)

Answer:
<u>Option 4:</u> 10d + 5
Step-by-step explanation:
Given the algebraic expression, 5(2<em>d</em> + 1), which represents the fines per day, <em>d</em>, for overdue books.
In order to determine the equivalent algebraic expression of 5(2<em>d</em> + 1), we must distribute 5 into the terms inside the parenthesis:
5(2d<em> </em>+ 1)
= 5(2d) + 5(1)

Therefore, the equivalent expression is: 10d + 5.
