Suppose you could climb to the top of the great pyramid. which route would be shorter, a route along a lateral edge or a route along the slant height of a side? which of these routes is steeper? explain your answers.

Consider a regular pyramid. A pyramid has slant height, altitude, base, and a lateral edge. The lateral edge is always greater than the slant height. Therefore, if you climb to the top of the Great Pyramid, the route that is shorter is a route along the slant height of a side. 

X + y = 28  (sum of two numbers is 28)

x = 3y (x is three times y) 

this is the system of equation:

x + y  = 28
x - 3y = 0
