Answer: x=-10

Step-by-step explanation:

6(x-2)=5x+3x+8

6(x−2)=8x+8

6x−12=8x+8

−12=8x+8−6x

−12=2x+8

−12−8=2x

−20=2x

-20/2=x

-10=x

x=-10

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

Answer:

x = -10

Step-by-step explanation:

 6 • (x - 2) -  (8x + 8)  = 0

Pulling out like terms :

3.1     Pull out like factors :

  -2x - 20  =   -2 • (x + 10)

Equation at the end of step  3  :

 -2 • (x + 10)  = 0

Equations which are never true :

4.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    x+10 = 0

Subtract  10  from both sides of the equation :

                     x = -10

One solution was found :

                  x = -10

Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm
Schach [20]

Answer:

a) Surface area = 616 cm²

b) Volume = V = 1083 cm³

Step-by-step explanation:

Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm

a) Formula for surface area = Base area × 1/2(perimeter × slant height)

Base area = Base edge²

=( 16 cm)² = 256 cm²

Perimeter = Base edge × 3

= 16 cm × 3 = 48 cm

Hence:

Surface Area = 256 cm² + 1/2(48 × 15)

= 256 cm² + 360 cm²

= 616 cm²

b) Volume = 1/3 × Base area × Height

1082.758616785cm³

Approximately = 1083 cm³

Write an equation describing the relationship of the given variables. y varies inversely as the cube root of x and when x=125, y
notka56 [123]

Answer:

y = 40 / x^1/3

Step-by-step explanation:

Given that :

y α x^1/3

y = k * 1 / x^1/3

y = k / x^1/3

When x = 125 ; y = 8

8 = k / 125^1/3

Cube root of 125 = 5

8 = k / 5

8 * 5 = k ; k = 40

Hence, expression becomes :

y = 40 / x^1/3
