What conjecture can you make about the sum of the first 10 positive even numbers? . 2 =2 = 1 x 2. 2 + 4 = 6 = 2x3. 2+4+6 = 12 = 3x4. 2+4+6+8 = 20 = 4x5. 2+4+6+8+10 = 30= 5x6. . a] the sum is 9x10. b] the sum is 10x10. c] the sum is 11x12. d] the sum is 10x11

Why do interests rates on loans to be lower in a weak economy than in a strong one

Asix-sided number cube is rolled twice. what is the probability that the first roll is an even numbe and the second roll is a number greater than 4?

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.
