Answer:

x = 1/3

Step-by-step explanation:

15 = 1/2 + 3/2x + 10

15 - 1/2 -10 = 3/2x

9/2 = 3/2x

9 x 2x = 3 x 2

18x = 6

x = 6/18

x = 1/3

Answer:

x = 3

Step-by-step explanation:

15 = 1/2 + 3/2x + 10                  

14.5 = 3/2x + 10                      Subtract 1/2 to both sides

4.5 = 3/2x                               Subtract 10 to both sides

3 = x                                        Divide 3/2 to both sides

How many solutions are there to the equation below?<br> 8x + 47 = 8(x + 5)
qaws [65]

Answer:

there are 0 solutions to the equation

Step-by-step explanation:

To know how many solutions are in the problem, we have to solve for x and see what result we have left. According to the result, we will know how many solutions there are

8x + 47 = 8(x + 5)

8x + 47 = 8*x + 8*5

8x + 47 = 8x + 40

8x - 8x = 40 - 47

0 = -7

As we can see we are left with an equality that is not fulfilled, this means that there is no solution to the problem, at least in the field of real numbers

Mrs. Nally's swimming pool is 10 feet by 6 feet. She paves the area around it with a sidewalk x feet wide, using 80 square feet
andrew11 [14]

Answer:

The sidewalk is 2 feet wide

Step-by-step explanation:

The area of the sidewalk is given as 80 square feet

The length and width of pool

including side walks will be;

10 + 2x and 6 + 2x

To get the area of the side walk

That will be area of total minus area of the pool

That will be ;

(10 + 2x)(6 + 2x) - 10(6) = 80

60 + 12x + 20x + 4x^2 - 60 = 80

4x^2 + 32x -80 = 0

x^2 + 8x -20

x^2 + 10x - 2x - 20 = 0

x(x + 10) -2(x + 10) = 0

(x-2)(x + 10) = 0

x = 2 or -10

since width cannot be negative;

The sidewalk is 2 feet wide
