A

given the 2 equations

2x + y = - 2 → (1)

x + y = 5 → (2)

subtract (2) from (1) term by term to eliminate y

(2x - x ) + (y - y ) = (- 2 - 5 )

x + 0 = - 7 ⇒ x = - 7

substitute x = - 7 in either of the 2 equations and solve for y

(2) : - 7 + y = 5 ( add 7 to both sides )

y = 5 + 7 = 12 → A

The perimeter of a isclose triangle is 24in and the length of the side is 4 in find the 2 other sides

Scrat [10]

Answer:

10 inches

Step-by-step explanation:

Given

Shape: Isosceles Triangle

$Perimeter=24\ in$

$Side = 4\ in$

Required

Find the length of the other two sides

Represent the other sides with x.

Since it is an isosceles triangle, 2 sides are equal.

So, we have:

$x + x + 4 = 24$

$2x + 4 = 24$

Collect Like Terms

$2x = 24-4$

$2x = 20$

Divide both sides by 2

$\frac{2x}{2} = \frac{20}{2}$

$x = \frac{20}{2}$

$x = 10$

<em>The other sides are 10in each</em>
