A flagpole casts a shadow that is 9 feet. An office building casts a shadow that is 15 feet. If the building is 60 feet tall, how
tall is the flagpole?

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Sh what is the value of x? ox= 2.25 x = 11.25 ox= x = 22 1 (2x + 10) seo - (6x + 1) -- nie
