Write an expression for the perimeter of the triangle below.

jekas [21]

Answer:

8.9k

Step-by-step explanation:

We just have to add together the length of the three sides to find the perimeter of the triangle.

(1.8k-5)+(3.5+6.1k)+(k+1.5) = 1.8k-5+3.5+6.1k+k+1.5

Combine like terms.

1.8k-5+3.5+6.1k+k+1.5 = 8.9k + 0

= 8.9k

X-5y=2 and 9x+8=15 solve by substitution

lozanna [386]

$x-5y=2$
Hence $x=2+5y$ (Equation I)
$9x+8=15$ (Equation II)
Substituting Equation I in Equation II
$9(2+5y)+8=15$
$18+45y+8=15$
$26+45y=15$
$45y=-11$
Hence $y= - \frac{11}{45}$

Substituting this in Equation in I to get X

$x-5(- \frac{11}{45} )=2$
$x+ \frac{11}{9}=2$
$x= 2- \frac{11}{9}$
$x= \frac{17}{9}$
