Nancy bought an extra-large bag of 1,500 beads to make necklaces. when she got home, she found another bag with 660 beads in it. if she uses all of the beads and uses 60 beads per necklace, how many necklaces can she make?

Sum is 17 and their difference is 3

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

Solve the system of equations y= 3/2 - 1, -x+ y =-3
