Veseljchak [2.6K]
First you plug in for x,

2(y-3)+y=12

Then you solve for y
2y-5+y=12
-10y+y=12
-9y=12
-9y/9=12/-9
y=-1.333333333333333333333333333333333333333333333333333333333

An expression represents the perimeter, in centimeters, of this triangle is 6q + 8r - 5s.

<u>Given the following data:</u>

  • a = (q + r) centimeters.
  • b = (5q - 10s) centimeters.
  • c = (5s + 7r) centimeters.

<h3>What is a triangle?</h3>

A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.

<h3>How to calculate the perimeter of a triangle?</h3>

Mathematically, the perimeter of a triangle can be calculated by using this formula:

P = a + b + c

<u>Where:</u>

a, b, and c are length of sides.

Substituting the given parameters into the formula, we have;

P = q + r + 5q - 10s + 5s + 7r

P = 6q + 8r - 5s centimeters.

Evaluate . | 6a |- 10 for a = - 7
Ilia_Sergeevich [38]
The answer would be 32. This is because once you input -7 you multiply -7 and 6 and end up with -42 but since it is in absolute value it turns into positive 42. Now it is 42 - 10. At this point all you do is subtract which will get you 32. Hope this helps ; )
