Akira used 10 centimeters to wrap 5 presents. how many presents did akira wrap if she used 18 centimeters of tape? solve using unit rates.

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 somebody 1. what is the formula for finding the vertical distance between two points on a coordinate plane?

Solve for x: 5/3 x = 20/21 it's fraction. remember to simplify your fraction
