1. Solve by using the Elimination method for solving systems of equations.
2. Top equation, minus, the other equation on the bottom. (4x-9y=-21)-(4x+3y=-9)
3. Subtract like terms.
4x-4x = 0
-9y - 3y = -12y
-21 - -9 = -30
4. Isolate for y
y= -30/-12 =5/2
5. Plug the value of y into original equation and isolate for x.

A square poster has a side length of 26 in. Drawn on the poster are four identical triangles. Each triangle has a base of 8 in.
Firdavs [7]
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.

Divide the area of the combined areas and the total area to find the probability of landing on a triangle.

A = 1/2bh
      1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)

A = bh
     26 x 26
A = 676 square inches

128/676 = 0.189

There is an approximate probability of 0.19 of hitting a triangle.
