Alan thought that the 2 should go next to the 9 to make 92, and the 8 should go next to the 1 to make 18. He used his Base Ten Blocks to help him draw the figure below to justify his answer. Where in Alan’s picture can you see the 2 (of the 92) and the 8 (of the 18)? What about the 9 of the 92 and the 1 of the 18? What part of the picture represents the product? Label the picture below where you see each of the numbers.

Which of the following is the explicit rule for a geometric sequence defined a recursive formula of a -5a for which the first term is 23?

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
