What is the solution to this system of equations?
x − 2y = 15
2x + 4y = -18

a. x = 1, y = -6

b. x = 1, y = -7

c. x = 3, y = -6

d. x = 3, y = -7

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4

Pllz me also i will report if you are in for the 1. complete the table by converting each decimal to a fraction. repeating decimals. 0.31 0.125 0.1607 2. describe any patterns you noticed when converting the decimals in the table above.
