They are parallel since x and y are bottom and top
Answer:
x = 17
Step-by-step explanation:
x and 163 are same- side interior angles and are supplementary, sum to 180°
x + 163 = 180 ( subtract 163 from both sides )
x = 17
The annual discount is 3%, therefore the total discount for 1 year would be:
4300 × 3 ÷ 100 = 129$
Now, you can set a proportion:
discount : annual discount = loan days : days in one year
21 : 129 = x : 360
x = 21 × 360 / 129 = 58.6 days
Hence, the loan duration was 60 days.
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.
