Thank you..​

Answers

Answer:

(A) and c

(B) and a

(C) and d

(D) and b

Step-by-step explanation:

these are from the calculations i got, what you do is minus the two answers you have to find n

For equations,

A) -1.4 n + 2.1 = 6.58 then n = 3.2

B) 4 n - 2 3/4 = -22 3/4 then n=24

C) 5.7 n + 4.1 = 2.96 then n=-0.2

D) n/8 + 1/2 = -3 1/2 then n=24

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

A) -1.4 n + 2.1 = 6.58

Subtract 2.1 on both sides

1.4n=6.58-2.1

1.4n=4.48

Divide both sides by 1.4

n=3.2

B) 4 n - 2 3/4 = -22 3/4

4n-11/4=-85/4

4n=85/4+11/4

4n=96

Divide both sides by 4

n=24

C) 5.7 n + 4.1 = 2.96

5.7 n  = 2.96- 4.1

5.7n=-1.14

n=-0.2

D) n/8 + 1/2 = -3 1/2

n/8 = -3 1/2-1/2

n/8 = -5/2-1/2

n/8 = -3

n=-24

Hence, equations A) -1.4 n + 2.1 = 6.58 then n = 3.2

B) 4 n - 2 3/4 = -22 3/4 then n=24

C) 5.7 n + 4.1 = 2.96 then n=-0.2

D) n/8 + 1/2 = -3 1/2 then n=24

What is the mean?

Answers

15.25, you add them all together which would equal 61 and then divide by 4 since there’s 4 numbers

Answer:

The mean is 15.25.

Step-by-step explanation:

First, we need to be sure we know that the mean is the average number in the group of numbers. That doesn't mean the most repeated or the number in the middle. Simply, the average.

To find the mean of a group of numbers you simply add them all together and divide by the number of numbers. So, let's solve.

12 + 14 + 17 + 18

= 61 ÷ 4

= 15.25

So the mean of 12, 14, 17, and 18 is 15.25.

Hope this helps! If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. :) Stay safe and please mark brainliest!

Find the values of x and y

Answers

Answer:

x = 8

y = 21

Step-by-step explanation:

The angle (7x + 12)° and the angle (12x-28)° are alternate interior angles and so has got the same measurement

7x + 12 = 12x - 28

12 + 28 = 12x - 7x

40 = 5x divide both sides by 5

8 = x

The sum of angle (12x - 28)° and (9y - 77)° must be equal because they make a straight line with the measure of 180°

12x - 28 + 9y - 77 = 180 we already found the value of x as 8 so let's rewrite the equation

12 × 8 - 28 + 9y - 77 = 180

96 - 28 - 77 = 180 add like terms

9y - 9 = 180

9y = 189 divide both sides by 9

y = 21

15/ 25

Step by step explanation

With exponents you don’t multiply them by the number you multiply them the amount of times the number says so if a is one you multiply 1×1×1 which is one then you move on to B both times has it exponent of 2 so 3×3 is nine and 9×1 is 10. And since there is no exponent Over C, you can just add 10+5 which is 15

Now on the bottom half you see that C doesn’t have an exponent so we can figure out a is 1 then, do you see that b has the same exponent of two we are just going to bring that nine down to the lower half now as you can see, C has an exponent 5×5×5 is 15 and 15+10 = 25

At a high school football game, admission is $5 for students and $10 for non-students. There were 500 people at the first game, and the school made $4,000 from admissions. In this activity, you will find the number of students and non-students at the game.

Please write the two equations algebraically and then solve :)

Answers

Answer:x = 200 students

y = 300 non-students

Step-by-step explanation:

5x + 10y = 4000

x + y = 500

Set y = 500-x

5x + 10(500-x) = 4000

5x + 5000-10x

-5x + 5000 = 4000

-5x = -1000

x = 200 students

y = 300 non-students

Let's double checks

5(200) + 10(300)

1000 + 3000 = 4000

If two 12-sided dice are rolled, what is the probability that both numbers will be even?

The probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

Given that two 12-sided dice are rolled and need to calculate the probability of getting an even number.

Number of favorable outcomes = 6 x 6 = 36

Number of sample = 12 x 12 = 144

The probability of getting an even number will be calculated as:-

Probability = Number of favorable outcomes / Number of sample

Probability = 36 / 144

Probability  = 1 / 4

Therefore, the probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.
