If you round $4,329.97, $452.28, and $279.34 you would get $4,000, $500, and $300. If you add $452.28 (rounded to $500) twice to $4,329.97 (rounded to $4,000) then you would get $5,234.56 which you would round to $5,000. Then when Alexa withdrawals $279.34 (rounded to $300), you subtract $279.34 from $5,234.56 (rounded to $5,000) and you get $4,955.22 which would be rounded up to $5,000. This proves that Alexa's estimate was reasonable.
Hello,
For the first question, congruent triangles have congruent corresponding angles and sides. For option choice A, MN corresponds with PQ, not PR, so it is incorrect to conclude that they are equal. The answer is A.
For the second question, we are given two angles and an not included side, so it would be AAS.
The answer is A, I believe.
Hope this helps!
The answer for this question is d

The whole parallelogram is 360. The two obtuse angles are each 71+45=116, which adds up to 232.
The two acute angles together add up to 360 (the whole parallelogram) minus 232 (the two obtuse angles), which is 128. The two acute angles are equal in a parallelogram, so you can divide 128 by 2 to get one of the angles, which is 64.
This means that angle BAD is 64. BAD is just the sum of BAC and CAD, so you can now figure out BAC:
BAD=BAC+CAD
64=BAC+27 (the 27 is given)
BAC=64-27
BAC=37
