If 8 is added to twice a number and this sum is multiplied by 3, the result is the same as if the number is multiplied by 3 and 9 is added to the product. What is the number?

Which expression can be used to determine the slope of the line that passes through the points -6, three and one, -9

In a rectangle klmn, km = 6x + 16 and ln = 49. find the value of x

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
