Jane has a checkbook balance of $68.00. she then writes two checks, one for $5.00 and one for $62.50. she also deposits $75.00. she then uses her calculator to determine her new balance. which of the following is the correct series of keys she should press? a.) 6 8 + 7 5 – 5 – 6 2 . 5 0 b.) 6 8 + 7 5 – 6 2 5 0 – 5 = c.) on/c 6 8 – 5 – 6 2 . 5 0 + 7 5 = d.) on/c 6 8 + 7 5 = 5 = 6 2 . 5 0

Nina has prepared the following two-column proof below. she is given that ∠oln ≅ ∠lno and she is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno step statement reason 1 ∠oln ≅ ∠lno given 2 draw oe as a perpendicular bisector to ln by construction 3 ∠leo ≅ ∠neo transitive property of equality 4 m∠leo = 90° definition of a perpendicular bisector 5 m∠neo = 90° definition of a perpendicular bisector 6 le ≅ en definition of a perpendicular bisector 7 δole ≅ δone side-angle-side (sas) postulate 8 ol ≅ on cpctc nina made two errors in the proof. identify and correct the errors.
