Answer to Q6:

x = 3

Step-by-step explanation:

Given equation is :

7x = 6+5x

We have to find the value of x by simplifying above equation.

Adding -5x to both sides of above equation, we get

7x-5x = 6+5x-5x

Adding like terms, we have

2x = 6+0

2x = 6

Dividing by 2 to both sides of above equation, we get

2x/2 = 6/2

x = 3 Which is the answer.

Answer to Q7:

x = 6

Step-by-step explanation:

We have given an equation.

30 = 4x+6

We have to find the value of x.

Adding -6 to both sides of above equation , we get

30-6 = 4x+6-6

24 = 4x+0

24 = 4x

Dividing by 4 to both sides of equation, we have

24/4 = 4x/4

6 = x

Swapping equation , we have

x = 6 which is the answer.

Answer to Q8:

x = 4

Step-by-step explanation:

Given equation is:

2(x+4) = 16

We have to find the value of x by simplifying it.

Distributing 2 to parentheses of above equation, we get

2x+8 = 16

adding -8 to both sides of above equation, we have

2x+8-8 = 16-8

2x+0 = 8

2x = 8

dividing by 2 to both sides of above equation, we have

2x/2 = 8/2

x = 4 which is the answer.

Answer to Q8:

x = 3

Step-by-step explanation:

We have given following equation.

7+5x = 3x+13

We have to find the value of x by simplifying above equation.

Adding -3x to both sides of above equation, we get

7+5x-3x = 3x+13-3x

adding like terms, we get

7+2x = 13

adding -7 to both sides of above equation, we get

-7+7+2x = -7+13

2x = 6

dividing by 2 to both sides of above equation , we have

2x/2 = 6/2

x = 3 which is the answer.

Answer:

Find the value of x(attachment 11)

6)

7x = 6 + 5x

7x - 5x = 6

2x = 6

x = 6/2 = 3

7)  

30 = 4x + 6

4x = 30 - 6 = 24

x = 24/4 = 6

8)

2(x + 4) =16

x + 4 = 16/2 = 8

x = 8 - 4 = 4

9)

7 + 5x = 3x + 13

5x - 3x = 13 - 7

2x = 6

x = 6

<u>Find the area(From attachment 2)</u>

1) Area = 4* 5 = 20

2)Area = 7 * m = 7m

3). Area = 3* a = 3a

4). Area = x*x = x²

5). Area = 4*x + 3* 4 = 4x + 12

6). Area = 7*a + 7*9 = 7a + 63

7). Area = 3x*x + 2*3x = 3x² + 6x

<u>expression of line segment</u>

8) x + 9

9).  x + 4

10). a + 2

A ball is chosen at random from a bag containing 150 balls that are either red or blue and either dull or shiny. There are 36 re
tino4ka555 [31]

Answer:

The probability of the chosen ball being shiny conditional on it being red is; 0.375

Step-by-step explanation:

Let A be the event that a red ball has been chosen

Let B be the event that a shiny ball has been chosen

Let S be the total outcomes = 150 balls

Thus;

P(A ∩ B ) = 36/150

A ∩ B' = 150 - 36 - 54

A ∩ B' = 60

Thus; P(A ∩ B') = 60/150

P(A') = 54/150

P(A) = (150 - 54)/150 = 96/150

Thus, probability of the chosen ball being shiny conditional on it being red is;

P(B | A) = P(B ∩ A)/P(A)

Thus; P(B | A) = (36/150)/(96/150)

P(B | A) = 0.375

I need help with geometry
satela [25.4K]

Answer:

45 is the answer

Step-by-step explanation:

first you have to know the sum of interior angle of that pentagon (540)

then add the all angle.

148 + x + 112 + 90 + 3x + 10 = 540.

or, 360 + 4x = 540

or, 4x = 540 - 360

or, 4x = 180

or, x = 180/4

or, x = 45

hope it will help you☺✌
