1/2 z = -3/4 + 1/4 z
1/2 z - 1/4 z = -3/4
1/4 z = -3/4
z = (-3/4)/(1/4)
z = -3/4 x 4/1
z = -3
The two white triangles have areas of 1/2 x 3 x 10 and 1/2 x 6 x 10 = 15 + 30 = 45 cm^2
The shaded area will be 10 x 10 - 45 = 55 cm^2
The percentage shaded = 55 / 100 x 100% = 55%
When solving a system of equations by graphing it, and there is no intersection between the lines, then it has no solutions.
A man has 21 sheep, one out of every 4 are red, how many are red
21/4 = 5.25
A man has 21 bricks he glues every 4 pieces together how many pieces does he have now
