Answer:

Speed of Jane = 57.5 mph

Step-by-step explanation:

Paul  leaves her house at 12:00 pm and drives south to a state park. He arrives at 2:30 p.m.

Time taken = 2:30 p.m - 12:00 pm = 2:30 hours = 2.5 hours

The driving distance from the house to the state park = Speed of Paul x  Time taken by Paul

S₁ = Speed of Paul x  2.5

At 12:00 p.m. , Jane leaves her house and drives north to the beach. She arrives at 1:30 p.m.

Time taken = 1:30 p.m - 12:00 pm = 1:30 hours = 1.5 hours

The driving distance from the house to the beach = Speed of Jane x  Time taken by Jane

S₂ = Speed of Jane x  1.5

The driving distance from the beach to the state park is 230 mi.

Let speed of Jane and Paul be u.

S₁ + S₂ = 230

2.5 u + 1.5 u = 230

4 u = 230

u = 57.5 mph

Speed of Jane = 57.5 mph

Answer:

B, D

Step-by-step explanation:

Angles 1 and 2 combined form a right angle, so the sum of their measures is 90°.  Therefore, they are complementary angles.

Since they share a common side and vertex and don't overlap, they are also adjacent angles.

Mrs.Scott decides that she would spend no more then $120 to buy a jacket and a shirt. If the price of the jacket was $20 more th
Leona [35]

Highest possible value of shirt = $25

Step-by-step explanation:

<u>DATA:</u>

Total amount to be spent = $120

Price of shirt = x

Price of jacket = 20 + 3x

<em>To find the price of the shirt, </em>

<u>Step 1: Find the value of x </u>

Price of shirt + price of jacket = Total amount to be spent

x + 20 + 3x <= 120

4x + 20 <= 120

4x <= 100

x <= \frac{100}{4}

x <= 25

<u>Step 2: Find the value of the shirt by substituting the value of x</u>

Price of shirt = x

Price of shirt = $25

Price of Jacket = 20 + 3x

Price of Jacket = 20 + 3(25)

Price of Jacket = 20 + 75

Price of Jacket = $95

Therefore, the highest possible price of the shirt is $25.
