A 36-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 3 times as long as as the first piece. If x represents the length of the first piece, find the lengths of all three pieces.

Explanation / Answer

Find the code for each country? The codes must add up to 114. There are 3 codes so 3 numbers that must add up to 114. 114 / 3 = 38 so the average number, or middle number, must be 38 Code A = 37 Code B = 38 Code C = 39 the left and right page numbers of an open book are two consecutive integers whose sum is 33, Find these page numbers. the smaller page number is? the larger page number is? Same strategy, 33 / 2 = 16.5 so the average of the two page numbers must be 16.5 Smaller page number = 16, Larger = 17 The sum of three consecutive integers is 204. What are the intergers? Use the same strategy. 204 divided by (3) = 68 so the integers are 67, 68, 69 If the sum of a number and four is tripled, the results is three less than twice the number. Find the number. x= Let the unknown number be "x" (x + 4)*3 = (2x - 3) 3x + 12 = 2x -3 x + 12 = -3 (subtract the 2x from both sides) x = 9 (add 12 to both sides)
