Write an equation to solve each problem. Lisa and Beth have babysitting jobs. Lisa earns $30 per week and Beth earns
$25 per week. How many weeks will it take for them to earn a total of $275?
To start, record what you know. Lisa earns $30 per week.
Beth earns $25 per week.
Total earned: $275
Describe what you need to find. an equation to find the number of
weeks it takes to earn $275 together

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.

middle maybe?
