Hey pls answer my simple question. <3

adult ticket would cost 4.5 after the 45% discount and the childs ticket would cost 2.4 after the 40% discount

(i converted 2/5 into a percentage which left me with 40%)

each time the family goes to the movies the family saves 9.1

(assuming its one adult and one child)

so 40/9.1= 4.39 and round it to 4

question A

adult ticket after discount=4.5

child ticket after discount=2.4

Question B

the family would have to go at least 4 times before they start saving money.

step-by-step explanation:

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
