Mathematics Series - Pre Algebra Multi-Cache

Mathematics can be subdivided into the study of quantity, structure, space, and change (i.e. arithmetic, algebra, geometry, and analysis).

Pre-Algebra is a common name for a course in middle school mathematics. In the United States, pre-algebra is generally taught between the fifth and eight grades. The objective of pre-algebra is to prepare the student for the study of algebra.

This is a two-part muti-cache. You will find at the re-director a 3-digits number. Use this number to solve pre-algrebra exercises in order to find the final cache at N29 32.DEF, W098 22.JKL

To complete the North coordinate (DEF), find the missing value in the proportion below; then, subtract this number from the number found on stage 1.

3/40=12/x

To complete the West coordinate (JKL) find the perimeter of an Equilateral triangle when one of the sides is equal 59.
