Which equation represents this number sentence? the product of 10 and a number is 3 less than the number. a. 10/n=n−3 b. 10/n=3−n c. 10n=3−n d. 10n=n−3

What are the solutions of the equation? 5z^2 + 9z - 2 = 0 a. 1, -2 b. 1, 2 c. 1/5, -2 d. 1/5, 2

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Rationalize the denominator- 12x/√x-10
