Answer: Simplifying

2x + 4 + 2x + 8 + 2x + 8 = 180

Reorder the terms:

4 + 8 + 8 + 2x + 2x + 2x = 180

Combine like terms: 4 + 8 = 12

12 + 8 + 2x + 2x + 2x = 180

Combine like terms: 12 + 8 = 20

20 + 2x + 2x + 2x = 180

Combine like terms: 2x + 2x = 4x

20 + 4x + 2x = 180

Combine like terms: 4x + 2x = 6x

20 + 6x = 180

Solving

20 + 6x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-20' to each side of the equation.

20 + -20 + 6x = 180 + -20

Combine like terms: 20 + -20 = 0

0 + 6x = 180 + -20

6x = 180 + -20

Combine like terms: 180 + -20 = 160

6x = 160

Divide each side by '6'.

x = 26.66666667

Simplifying

x = 26.66666667

The lengths of 3 pieces of rope in the ratio 3:5:7. if the longest piece of rope is 56 inches long, how long is the shortest pie

Stolb23 [73]

Ratio being 3:5:7
longest being 56 so
7x=56
x=8
multiply the other lengths by 8
3*8=24
5*8=40
making the final

Kira John and Ryan sent a total of 112 text messages during the weekend. Kira sent 8 fewer messages than Ryan. John sent 4 times

Softa [21]

Answer:

Kirasent 16 and Ryan sent 96

Step-by-step explanation:

I got this because Kira is x-8 and Ryan is 4x. 4x-x-8=112 is equal to 5x=120. So x=24.Kira has 16 when plugging in x and Ryan has 96 because 4 times 24 is 96.

What is the value of f (6) ?

Marta_Voda [28]

$\huge{ \boxed{ \tt{Solution :-}}}$

$\sf{f(x) = \dfrac{ x^2 - 4x }{20}}$

$\sf{What\: is\: the\: value \:of \: f(6)?}$

Now we solving it :

$\sf { : \implies{f(x) = \dfrac{ x^2 - 4x }{20}}} \\ \\ \sf { : \implies{f(6) = \dfrac{ 6^2 - 4 \times 6}{20}}} \\ \\ \sf { : \implies{f(6) = \dfrac{ 36 - 24}{20}}} \\ \\ \sf { : \implies{f(6) = \dfrac{ 12}{20}}} \\ \\ :\implies{\boxed {\tt{f(6) = \dfrac{ 3}{5}}}}$

$\bf {\therefore{The\:value\:of\:f (6)\:is\:\dfrac{ 3}{5}.}}$

$\rule {307}{2}$
