The soccer club has planned a trip to a tournament. the cost of the van is $192. when 2 students who are not members of the club join the trip, the transportation cost per person drops by $3.20. how many soccer club members are going to the tournament?

10

Step-by-step explanation:

Let N be the number of members of club.

The cost of the van is $192.

Let p be the cost per person

So,Cost per person =  --A

Now we are given that When 2 students who are not members of the club join the trip, the transportation cost per person drops by $3.20.

So, equation becomes:  ---B

Using A

Since number of members cannot be negative .

So, the number of members is 10 .

Hence there are 10 members in the club.

your answer is d 2,500

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.
