Answer:
We need to find which expressions are equivalent to
,
or neither.
: We extract the greatest common factor which is 6. Remember, when we extract a GCM, we divide each term by it.

Therefore, this expression is equivalent to neither of the given expressions.
: We just need to apply the distributive property.

Therefore, this expression is equivalen to
.
We use the same process to the other expressions.



, equivalent to neither.
Sally bought 5 apples at the store. Her friend, jenny, bought 4 times as many apples as Sally. Jonathan bought 6 more apples than Sally. How many apples did Jenny buy?
Answer: The numbers can be added in any order.
Step-by-step explanation:
To calculate the total time that Colin spent traveling from his house to the hotel the numbers can be added in any order because time is a scalar quantity. It cannot be negative.
A scalar quantity is the quantity which has only magnitude but not the directions. For example temperature (vector quantity), it can be both positive and negative but time cannot be negative, thus it is a scalar quantity.
Answer:
1 mile = 15 seconds
Step-by-step explanation:
3 minutes and 15 seconds = 3 min + 15 sec
1 minute = 60 seconds
15 seconds =15/60 = 0,25 min
then
3minutes and 15 seconds = 3.25 minutes
13miles in 3 minutes and 15 seconds
= 13 miles / 3.25 minutes
= 4 miles / 1 minute
every minute Jose ran 4 miles
then:
4 miles is a 1 minute
1 mile is a T minutes
T = 1*1/4
T = 1/4 minute
1 minute = 60 secomds
1/4 minute = 60*1/4 = 60/4 = 15 seconds
