Layla had the higher score by 20 points.

Step-by-step explanation:

Given,

Points for correct answer = 10 points

Points for incorrect answer = 20 points

Loss means subtraction;

Therefore,

Total points of Ji = Correct answers*10 - Incorrect answers*20

Total points of Ji = 7*10 - 3*20

Total points of Ji = 70 - 60

Total points of Ji = 10 points

Total points of Layla = Correct answers*10 - Incorrect answers*20

Total points of Layla = 5*10 - 1*20

Total points of Layla = 50 - 20

Total points of Layla = 30 points

Difference = Points of Layla - Points of Ji

Difference = 30 - 10 = 20 points

Layla had the higher score by 20 points.

I really need help with this question
Sergeu [11.5K]

Answer:

39

Step-by-step explanation:

I assume the father's age is a 2-digit number. He is not 9 years old or younger, and he is not 100 years old or older.

The sum of the digits of a two-digit number goes up by 1 from one number to the next unless the number ends in 9.

For example, from 17 to 18, the sum of the digits goes from 8 to 9.

If the number ends in 9, for example, 29, the digits add to 11. Then the next number is 30, and now the sum of the digits is 3, which is less than 11.

The father's age now is a number whose sum of digits is not only greater than the sum of the digits next year, but it is 3 times greater.

Let's look at 2-digit number and the next number and the sum of their digits.

19, 20; sums: 10, 2; 10/2 = 5, not 3

29, 30; sums: 11, 3; 11/3 ≠ 3

39, 40; sums: 12, 4; 12/4 = 3

Answer: The father is 39 years old.

What is the interval notation for the compound inequality? x is less than or equal to -4 or x is greater than or equal to 5?
Tems11 [23]

x is less than or equal to -4 or x is greater than or equal to 5

x <= -4 or x>= 5

There is no intersection of both inequalities when we graph it in number line So, we write the interval notation separately for each inequality

for x<=-4 , x starts at -4  and goes to -infinity because we have less than symbol. Also we have = sign so we use square brackets

Interval notation is (-∞ , -4]

for x>= 5 , x starts at 5  and goes to infinity because we have greater than symbol. Also we have = sign so we use square bracket at 5

Interval notation is [5 , ∞)

Now combine both notation by a 'U' symbol Union

(-∞ , -4] U [5 , ∞)
