WORD PROBLEMS (FROM CLASS TODAY) 1) One number is 5 more than twice another, and their sum is 23. What are the numbers? Let x = the first number x + (2x + 5) = 23 The numbers are 6 and 17 2) One number is six less than seven times another. If the sum of the two numbers is -6, find the numbers. Let x = the first number x + (7x – 6) = -6 The numbers are 0 and -6 3) The sum of four consecutive integers is 1 more than the third. Find all four numbers. Let x = first integer So x + 1 = second integer and x + 2 and x + 3 are the third and fourth integers respectively x + (x+1)+(x+2)+(x+3) = (x + 2) + 1 4) The width of a rectangular garden is 8 feet less than its length. If the garden is fenced in with 72 feet of fencing, what are the dimensions of the garden? -1, 0, 1, 2 2L + 2(L-8) = 72 14 by 22 5) The length of a rectangle is 1 more than 3 times the width. If the width is increased by 2 and the length is doubled, the new perimeter is 3 less than 5 times the original length. Find the original dimensions. W = original width 2(x+2) + 2[(2(3x+1))] = 5(3x + 1) – 3 6) A toy store sells puzzles for $8 each and games for $19 each.
