Answer:
22 and a half weeks
Step-by-step explanation:
We are told that Nilda owes $250 and has been earning $25 per week to catch up and start saving.
Also, Karla has saved $200 and has been saving an extra $5 per week to slowly build her savings.
Let the number of weeks they save for be represented as x.
Therefore, for them to have the same amount of money after x weeks,
25x - 250 = 200 + 5x
The left hand side represents Nilda's situation (250 is being deducted because she owes $250) while the right hand side represents Karla's situation (the 200 is added because she already owns $200).
Solving for x:
25x - 250 = 200 + 5x
Collecting like terms:
25x - 5x = 250 + 200
20x = 450
x = 450 / 20 = 22.5 weeks
Hence, they would both need to save for 22 and a half weeks to have the same amount of money.
Answer:
-1
Step-by-step explanation:
If a line is parallel on a graph, then that means that they will descend/climb at the same rate. Therefore, the slope of this line is also -1.
Hope this helped!
If length = a, width = b
if double both a and b will double its area?
area of a rectangle is ab
if double both a and b then the area is (2a)(2b) = 4ab (then peter is wrong because the area will be 4 times not double)
