Solve for b: 3.5b + (-8) = (-6.25b) - 6.5

A b = .15

B b = -.25

C b = 9.75

D b= .85

Solve for x:

-5x + 3 > (-7x) - 12

A x > -7.5

B x < -7.5

C x > 15

D x < -15

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.

#12 the answer is the third option

wouldn't that be a) 1

4=4x then divide 4 on both sides and you get x=1
