What is a terminating decimal?
Arte-miy333 [17]
A terminating decimal has digits that end. They do not go on forever. For example, 0.125 has only 3 decimal digits and does not keep on going like 1/3



A rational number is a number that canbe expressed as p/q where p and q are both integers. But q cannot equal to 0.



All terminating decimals are rational numbers, but not all rational numbers are terminating decimals. For example 1/4, which equals to 0.25 is both a rational number and a terminating decimal. On the other hand, 1/3 is a rational number but is not a terminating decimal.

Your friend loans you $550 to buy a PS5. They are going to charge you 3% interest rate. After some time you pay your friend back
tatuchka [14]

Answer:

2 years

Step-by-step explanation:

3% of $550 = 0.03 * $550 = $16.50

3% interest on $550 for 1 year is $16.50

$33/$16.50 = 2

Since 2 * $16.50 = $33, the loan was for 2 years.

Your doing the Distributive Property. So in this equation your distributing the first 2 on the outside of the parenthesis, so this first section of your problem after distributing is 6n+8. Next distribute the -2 to the 2n and 5. DON'T FORGET THE NEGATIVE. So it would look like 6n+8-4n-10. Then combine like-terms. so 6n-4n = 2n. Then 8-10=-2. Your final answer should be 

2n-2.
Hope this helped.
