Cole has $5 and $20-bills in his wallet. He has 7 more $5-bills than $20-bills. Let x be the number of $20-bills. If Cole has a total of $310 in his wallet, then algebraically find the value of x. ​

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
