Answers

3. AC, AB

Step-by-step explanation:

A line segment consists lf a line with two endpoints(dots). AC is a line segment and so is CB but that isn't an option sl the next best thing is AB because it is also a line segment

The line segments are AB, AC, and BC. Then the correct option is C.

What is a line segment?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

A line segment in mathematics has two different points on it that define its boundaries.

A line segment is sometimes referred to as a section of a path that joins two places.

There are 3 points A, B, and C on the line.

Then the line segments are AB, AC, and BC.

Then the correct option is C.

The students in Ms. Douglas’ class worked so hard this year that she has planned a surprise, end-of -year trip for them to a local amusement park. The school principal allows Ms. Douglas to spend a budget of $500 on the trip.
So far she knows :
A coach bus costs $180 to transport them to and from the park.
Price of admission to the park is $15 per person

Part A : Write an inequality that describes that how many students Ms. Douglas can bring on the trip. Define the variable


Part B: Solve the inequality and explain the solution in the context o the problem

Answers

Answer:

Part A: 180+15x=500

B: x = 21.333 or 21

Step-by-step explanation:

So in part A since you have 500 to spend and 180 goes to the coach bus, you are left with $ 320 to spend on the students and when you divide 320 by 15, (since the tickets for admission are $15) you end up with 21.333, but since you cant bring .333 of a student on a trip you can bring 21 students, but you can buy 21.333 tickets.

Answer:
A) 15x+180 ≤ 500
B) 33 people can go on the trip to not exceed the budget.

Steps:

15x+180 ≤500
Subtract 180 from both sides

15x ≤ 500
Divide both sides by 15 to isolate x(make sure to flip the sign since you are multiplying)

x ≥ 33.333

Therefore, only 33 people can go on the trip to not exceed the budget.
