Answer:

In Japan, the average ticket costs $17.73.

In Switzerland, the average ticket costs $13.45

Step-by-step explanation:

80.09-75.81=3j+2s-(2j+3s)

4.28=j-s

So a ticket from Japan costs $4.28 more than a ticket from Switzerland. so we can write the equation:

3s+2(s+4.28)=75.81

5s=67.25

s=13.45, j=13.45+4.28=17.73

Nadya [2.5K]

Based on the data, the median time it takes players to complete the game is 1148 minutes.

<h3>What is the median?</h3>

It is the mathematical value that is the middle when values are sorted.

<h3>How to find the median time?</h3>
  • Organize the values

457 - 548- 866 - 952 - 976 - 1037 - 1148 - 1235 - 1245- 1431-1486 - 1759 - 1864

Identify the value of the middle

Considering there are 13 values, the value of the middle is the value number 7 or 1148.

Note: This question is incomplete because the data is missing, below I attached the missing section,

4(5x + 9)^2 – 33 = -21
ozzi

Answer:

x = sqrt(3)/5 - 9/5 or x = -9/5 - sqrt(3)/5

Step-by-step explanation by completing the square:

Solve for x over the real numbers:

4 (5 x + 9)^2 - 33 = -21

Add 33 to both sides:

4 (5 x + 9)^2 = 12

Divide both sides by 4:

(5 x + 9)^2 = 3

Take the square root of both sides:

5 x + 9 = sqrt(3) or 5 x + 9 = -sqrt(3)

Subtract 9 from both sides:

5 x = sqrt(3) - 9 or 5 x + 9 = -sqrt(3)

Divide both sides by 5:

x = sqrt(3)/5 - 9/5 or 5 x + 9 = -sqrt(3)

Subtract 9 from both sides:

x = sqrt(3)/5 - 9/5 or 5 x = -9 - sqrt(3)

Divide both sides by 5:

Answer:  x = sqrt(3)/5 - 9/5 or x = -9/5 - sqrt(3)/5
