Marco owed his father $220 and began paying him back $20 at the end of each week, beginning November 1. Joni owed her father $120 and began paying back at the end of each week, beginning on the same day. What Marco owed his father in dollars at the end of n weeks can be represented by f (n) = 220 - 20 n. What Joni owed her father in dollars at the end of n weeks can be represented by g (n) = 120 - 10 n. Find the value of n for which f (n) = g (n). What does that value mean in this situation? After weeks, Joni and Marco each owed their fathers the same amount.​

Isee the amount was $90.00 then reduced to $75.00 , what is the percent ?

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
