7) 43 is 31% of what number?
8) 105 is 42% of what number?​

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

X2 + y 2 = 36 x + y = 6 solve the system of equations.
