Answer: B
Explanation:
14+7
this is addition, so we are adding 7 to our original quantity of 14 so we're looking for an example where you get 7 more than you originally had.
if Aja had 14 legos and her friend gave her 7 more, she just added 7 more to her 14 legos. (14+7)
why the other equations don't work
A. Aja had 14 legos, but she lost 7 of them.
Aja is losing 7 legos, we aren't adding to what she has, we are subtracting from her original total of 14. so this statement can't work for 14+7, because it is subtraction which would be 14-7.
C. Ajaj had 14 legos. She placed her legos equally into 7 bags.
in this statement, we are dividing her 14 legos equally into 7 bags. so this is division which would be 14÷7. so this can't be the statement to represent 14+7
D. Aja had 14 legos. She placed different amounts of L.
this isn't a full sentence but we can tell that it's not the answer because again, we are dividing the 14 legos into seperate bags. so this is division, not addition.
this is why the answer is
B. Aja had 14 legos. Her friend gave her 7 more legos.
