Answer:
x+(x+2) = 156
Step-by-step explanation:
Let x = 1st odd integer
x+2 = next odd integer
x+(x+2) = 156
2x+2 =156
Subtract 2
2x= 154
Divide by 2
x = 77
x+2 = 79

Answer:
x = 18 , y = 42
Step-by-step explanation:
27x + 14 = 500
-14 -14
This process above moves the +14 to the right hand side, making it negative 14
27x = 486
To find x, divide 27 by 486
x = 486/27
x = 18
600 = 12 + 14y
Move the 12 to the left hand side to remain the 14y
600 = 12 + 14y
-12 -12
588 = 14y
Divide 14 by 588
588/14 = y
y = 42

Each wall is 15*30 = 450
450* 4 walls = 1,800
Area of triangles are 15*15/2 = 112.5
112.5 * 4 triangles = 450
1,800 + 450 = 2,250
2,250/143 = 15.73
