14,300 = (700)(0.0725)(t)
14,300 = 50.75(t)
14300/50.75 = t
281.77 = t or t = 281.77
hope this helps :)
y = $185.30
x = the orignal cost minus 9% or .09. To increase an objects value by 9% you need to multiply by 1 + .09 or 1.09. So, x being increases by 9% would equal y or $185.30
1.09x = y
1.09x = $185.30
Divide both sides by 1.09
x = $170
It depends on which triangles you put together, if they are equilateral triangles, then its a diamond, if they are rectangle (right) triangles, then its a rectangle, if they are isosceles triangles, then its a really sharp diamond, and if they are scalene triangles, then the shape is like a common kite.
