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:

1. Emily scored 60 points in the first round

2. Emily scored minus 30 points in the second round

3. Emily's final score is 15 points.

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

Emily scored 60 points in the first round

3. Let's calculate the score of Emily in the second round:

Score = 4 * 20 - 11 * 10

Score = 80 - 110

Score = - 30

Emily scored minus 30 points in the second round

4. 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

Emily's final score is 15 points.

108=-12 - 4 (-5n+7)I need help

Andrei [34K]

108 = -12 + -4(-5n + 7)

108 = -12 + (7 * -4 + -5n * -4)

108 = -12 + (-28 + 20n)

108 = -40 + 20n

-20n = -40 + -108

-20n = -148

n = 7.4

Maria's account has a credit of $ 13, and Harry's account has a debit of $ 14. Which of the following statements are true? Selec

soldi70 [24.7K]

Answer:

A, Harry has $27 more.

Step-by-step explanation:

I could be wrong but.

1) debit cards are of your money, if you have $14 in your account it means you have $14 that you can spend without owing anything.

2) credit cards allow you to borrow money with the expectation that you pay it back. So if you have $13 of credit, you owe $13 which I guess could be seen as -$13.

3) the distance between -13 and 14 is 27.
