a) if AB = CD, then 3CD = 3(CD + 1) NOT TRUE
example: AB = CD = 1, then 3CD = (3)(1)=3 and 3(CD + 1) = 3(1 + 1) = 3(2) = 6
b) if AB = CD, then AB - CD = A - C + B - D NOT TRUE (it does not make sense because A, B, C and D are points)
c) if AB = CD, then AB + EF = CD + EF TRUE
because
AB = CD |add EF to both sides
AB + EF = CD + EF
d) if AB = CD, then 2AB = 2A + 2B NOT TRUE (it does not make sense because A and B are points).
Answer:
Ashley would have to pay an additional $608.52 in interest when the length of the loan changes from 3 years to 5 years.
Step-by-step explanation:
Although the problem gives us the initial amount of the balance ($4000) and the interest rate (13%), we are really only concerned with the total amount Ashley will make in payments in three years versus five years. If she pays $134.78 for three years, that is 36 months, or $134.78 times 36 which is equal to $4852.08. However, if she decides to take longer to pay it and instead pays $91.01 for five years, or 60 months, then her total amount paid would be $5460.60. To find the difference between these two, simply subtract $5460.60-$4852.08 to get $608.52.
Answer:
5 miles but she did walk part of another mile so that would be 5.35.
Step-by-step explanation:
you can take 3.25 and subtract that by 0.58 until you can't do it anymore. Also I didn't know if you wanted the exact amount which would be 5.35 but total miles is only 5. Hope this helps!
We assume that
.. (number in school)/(560 lunches sold) = (60 students sampled)/(40 eat lunch)
Then
.. (number in school) = 560*60/40 = 840
