Solve for c. ab - c = 9
Weegy: Q - 7 5/6 = 6 1/2 Q = 6 1/2 + 7 5/6 = ((13 X 6) + (47 X 2)) / (2 X 6) = (78 + 94) / 12 = 172/12 = 43/3 = 14 1/3 User: Use the listing method to write the following set. {x | x N, x Weegy: I assume you mean divided by and the answer would be 1 User: The length of a rectangle is 3 inches more than its width, and its perimeter is 22 inches. Find the width of the rectangle. Weegy: Let x be its width, then its length is (x + 3). perimeter = 2x + 2(x + 3) = 22, solve the equation we get x = 4. Its width is 4 inches. User: Given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line. Weegy: Given the line 2x - 3y - 5 = 0, the slope of a line that is perpendicular to this line is -3/2. User: A man invests a certain amount of money at 2% interest and $800 more than that amount in another account at 4% interest. At the end of one year, he earned $92 in interest.
