The perimeter of a triangle is 16x−6. If two sides measure 3x+2 and 4x−9, then how long is the third side?
Studentka2010 [4]

Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,

we know,

\hookrightarrow \: y + 3x + 2 + 4x - 9 = 16x - 6

\hookrightarrow \: y + 7x - 7 = 16x - 6

\hookrightarrow \: y = 16x - 6 - 7x + 7

\hookrightarrow \: y = 6x + 1

hence, measure of the third side is 6x + 1

6. What is the y-value to the solution of<br> y = 5x -4<br> y = 2x + 8?
Angelina_Jolie [31]

Answer:

y = 16, don't know if I'm 100% right but hope this helps.

Step-by-step explanation:

since they both equal Y they may be equal to each other

Then you would subtract 2x from both sides canceling it out on one side

2x + 8 = 5x - 4

-2x         -2x

This would make the equation 8 = 3x - 4

next you add the 4 from both sides

8  = 3x - 4

+4         +4

This will leave you with 12 = 3x

now you divide 3 from both sides and 12/3 = 4 makes X = 4

next you take (4) and plug it in to one of the equations

y = 2(4) + 8

y = 8 + 8

y = 16
