Leona spent $22.95 at the mall. she bought a t-shirt and a book. the book $12.25. how much did the t-shirt cost? a. write the equation that models the problem. b. solve the equation. c. answer the question.

Which of the following is a proper fraction? a. 9⁄8 b. 5⁄6 c. 7⁄3 d. 4⁄2

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Can someone check if i did this correct. it’s number 4 if you’re wondering.
