Megan has fifty quarters and dimes. Their total value is $9.80. Which of these systems of equations can be used to find the number of quarters (q) and dimes (d) Megan has? q + d = 50

0.25q + 0.10d = 9.80

q + d = 50

25q + 10d = 980
q = d + 50

25q + 10d = 980

q = d + 50

q + d = 9.80

idk but I need points sorry

q + d = 50

25q + 10d = 980

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
