TRANSLATING MATHEMATICAL STATEMENTS INTO EQUATION OR INEQUALITY
By translating the following statements to equation or inequality, the answers will be: 1. 78
= W(W+7); 2. n - 1 < 3n + 5; 3. 2(A + 4) > 26; 4. 
; and 5. 12,000 + 0.05n 
120,000.
In translating mathematical statement into equation or inequality, a basic understanding to the terms used is prerequisite. In the statement 1, the length is 7 longer than the width. Thus L is W + 7. The formula for the area of the rectangle is A = length times width or A = LW. In statement 2, the word "less than" means minus. In statement 3, we let n as the number or the unknown. In statement 4, it is computing for the average wherein we add all the scores and divided by the number or cardinality of the scores.
