Answer:
Subtraction property of equality.
Answer:
The correct answer is C. 54.
Step-by-step explanation:
Since Danielle started her postcard collection with 6 cards that she received from her uncle during his trip to France, and Danielle's uncle sends her 2 more cards each month as he travels for business, and the table below shows the relationship between the number of months Danielle has been collecting cards and the number of cards she has.
Number of Months Danielle
Has Been Collecting Cards Number of Cards in the
Collection
2 10
4 14
8 22
24?
To determine how many cards Danielle can expect to have after 24 months, the following calculation must be performed:
(24 x 2) + 6 = X
48 + 6 = X
54 = X
Therefore, after 24 months Danielle will have 54 cards.
X represents the amount of weeks:
7+x for Germany and 3+2x for Tony they have to be equal for them to run the same distance:
3+2x=7+x
-3 from each side:
2x=4+x
-x from each side:
x=4
They run the same distance on the fourth week, that distance is 7+4=11
Hope this helps :)
