Simplify it
Elena L [17]

Answer:

2. 33.25

Step-by-step explanation:

In order of operations you start with the part of the equation that is in parentheses.  So here you would start with 8.7+4.6. Now whenever there is a number just sitting outside the parentheses, you multiply it by the numbers inside of the parentheses.   So in this case, once you've added 8.7 and 4.6, you multiply your answer by 2.5 (which is outside of the parentheses.  Here is the solving process:

2.5<u>(8.7+4.6)</u>

<u>2.5(13.3)</u>

33.25
