Answer:

7x + 4 = 5x + 16 \\ 7x - 2x = 16 - 4 \\ 5x = 12 \\ x = 2.4

\\ y + 6  + (7x + 4) = 180 \\ y + 6 + 7 \times 2.4 + 4 = 180 \\  \\ y + 17 + 16.8 = 180 \\ y + 33.8 = 180 \\ y = 180 - 33.8 \\ y = 146.2

Emily participates in a trivia quiz show. In each round, 20 points are awarded for a correct answer and 10 points are deducted f
kirza4 [7]

Answer:

<u>1. Emily scored 60 points in the first round</u>

<u>2. Emily scored minus 30 points in the second round</u>

<u>3. Emily's final score is 15 points.</u>

Step-by-step explanation:

1. Let's review all the information given to us to answer the questions correctly:

Points awarded for a correct answer = 20

Points deducted for a incorrect answer = 10

2. Let's calculate the score of Emily in the first round:

Score = 7 * 20 - 8 * 10

Score = 140 - 80

Score = 60

<u>Emily scored 60 points in the first round</u>

<u>3. </u>Let's calculate the score of Emily in the second round:

Score = 4 * 20 - 11 * 10

Score = 80 - 110

Score = - 30

<u>Emily scored minus 30 points in the second round</u>

<u>4. </u>Let's calculate the final score of Emily:

Final score = (Score 1st round + Score 2nd round)/2

Final score = (60 + - 30)/2

Final score = (60 - 30)/2 = 30/2 = 15

<u>Emily's final score is 15 points.</u>
