We can determine the value of the adult ticket cost and student ticket cost by following these steps:

1. solve form one of the variables from one of the equations

Let's solve for a from 2a + 2s = 40

2a + 2s = 40

2a + 2s - 2s = 40 - 2s

2a = 40 - 2s

2a/2 = 40/2 - 2s/2

a = 20 - s

2. Replace the expression found and solve for s

4a + 5s = 87

4(20 - s) + 5s = 87

4×20 - 4×s + 5s = 87

80 - 4s + 5s = 87

80 + s = 87

80 - 80 + s = 87 - 80

s = 7

3. Replace 7 for s into a = 20 - s

a = 20 - 7

a = 13

Then, a = 13 and s = 7.

Then the adult ticket cost is $13 and the student ticket cost is $7

8. The travel members are voting for the American city they will visit next semester: New York (N), San Francisco (S), or Chicag
fiasKO [112]

9514 1404 393

Answer:

  • plurality: San Francisco
  • plurality with elimination: New York

Step-by-step explanation:

Using the plurality method, the city with the most first-place votes wins the selection. Here, that is San Francisco, with 16 votes. Behind that is New York with 14 first-place votes.

If elimination is used, the selection with the fewest first-place votes (Chicago) is eliminated from the table, and all rows below are shifted up. Now, the first place row has 16 votes for San Francisco and 18 votes for New York.

San Francisco wins the plurality election.

New York wins the plurality-with-elimination election.

Answer:

47 degrees

Step-by-step explanation:

You have a straight line, which has an angle measure of 180 degrees.

180-133=47

Your answer can come from the line with 133 on it because the two lines are parallel with a transversal line. Because the two lines are parallel, they have the same interior angle measurements.

Oksi-84 [34.3K]

Answer:

AREA= 198 mm

PERIMETER = 57mm

Step-by-step explanation:

1: to take out the perimeter , add all the sides i. e. 12+14+18+13=57

2: to take out the area use formula B*H i. e. base *height - area of a parallelogram

B=18

H=11

18*11=198

this is the area
