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. How much money was invested in each account? Weegy: Let the man invest an amount x at 2% interest. Then, [ he invests an amount (x+800) at 4% interest. Total simple interest for one year is x*2/100 + (x+800)*4/100 = 92 2x+4x+3200 = 9200 6x = 9200-3200 6x = 6000 x = 1000 So the man invested $ 1000 at 2% interest and $ 1800 at 4% interest. ] User: What is the algebraic expression for "the difference between seven times a number and three times that number"?
