Because 115 is on a line and a line equals 180, subtract 115 from 180 and you get x=65
Remark
Answer: The second one. The second step removes the brackets on the right. It uses the <em><u>distributive property</u></em> which puts back the common factor that was taken out of the two terms 6x and 24. Quite often the distributive property is useful when presenting a problem to be solved.
The associative property is more of an order thing and that is very useful sometimes as well what it says is that if you have three numbers a + b + c the order which you combine things does not matter.
For example 3 + 4 + 5 could be combined as 3 + 4 = 7; 7 + 5 = 12 or 3 + 5 = 8, 8 + 4 = 12.
The associative property is useful when adding fractions.
Answer: It depends on the terms.
Step-by-step explanation: In fraction terms 16 is equivalent to 4. In number terms 16 is a number larger than 4.
