Answer:

Step-by-step explanation:

I'll do them you arrange.

x + (x - 1) > 5

If you start with 3 you will see that the answer is that the left equals the right. So 4 is the smallest number x can have

3 + (3 - 1)>5

6 - 1 = 5 not something greater than 5

4 + (4 - 1) > 5

8 - 1 > 5

7 > 5 which is true.

Answer 4

5x - 3x > 9

2x > 9 x must equal 5

2*5 > 9

10 > 9

Answer 5

6x - 14 > 3 add 14 to both sides.

6x - 14+14>3+14

6x > 17 The answer to equality is just about 3. So three is the answer

6*3 > 17

18 > 17

Answer 3

2x - 1 > 0 Add 1 to both sides.

2x > 1 1 is the answer

2*1 > 1

2 > 1

Answer 1

So all you need do is place them in order. The last one goes first and then the second last one.

ε = {x: 2 x 30, x is an integer}, M = {even numbers}, P = {prime numbers}, T = {odd numbers} Find: I) MUP ii) M - T iii) P(MT) i

mariarad [96]

Answer:

Step-by-step explanation:

ε = {x: 2≤ x ≤30}

M = { even numbers} = {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}

P = { prime numbers} = {2,3,5,7,11,13,17,19,23,29}

T = {odd numbers} = {3, 5, 7, 9, 11,13,15,17,19,21,23,25,27,29}

1. M ∪ P = {2,3,4,5,6,7,8,10,11,12,13,14,16,17,18,19,20,22,23,24,26,28,29,30}

2. M - T =

n(M) - n(T)

15- 14 = 1

3. P(MT)

(MT) = M ∩ T = 0

P ∪ (M ∩ T ) = {2,3,5,7,11,13,17,19,23,29}

4. P' = not a prime number

T' = not odd number = M

P' ∪(M∩T')

P' ∪ {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}

= {2,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30}

There are 550 people at the school carnival.

Svet_ta [14]

Answer:

70% of the people at the fair are students

165 people are on the ride

Step-by-step explanation:

In order to find a percentage, take the fraction given, 385/550, and divide the numerator, 385, and divide it by the denominator, 550. Once completing this, we get 0.7

Next, we multiply the result by 100, and get 70, thus, 385 is 70% of 550.

To find how many people 30% of 550 is, we take the percentage and put it in a fraction with the denominator being 100(changes with size of fraction like a decimal, 300 would be over a denominator of 1000)

With 30/100, we then multiply by 550 with the equation looking like this:

30/100*550/1

Once we finish multiplying(typically using a calculator, although you can do it manually) we get 165, the value of how many people are on rides out of the total 550.

Convert the following equation to slope-intercept form y+5=1/2(x-8)

alexandr402 [8]

Answer: y = 1/2x - 9

Step-by-step explanation:

y + 5 = 1/2(x - 8)
y + 5 = 1/2x - 4 (distribute)
y = 1/2x - 9 (subtract 5 from both sides)
