2/3(x - 3) + 1/2x = -10

I worked out this much:

2/3x - 2 + 1/2x = -10


7/6x - 2 = -10


7/6x - 2+ 2 =-10 + 2


7/6x = -8

But I don't know what to do next. =\

Evette has 41 1/2ft of string. She wants to cut it into pieces 3 3/4 ft long. How many pieces of string will she have? How much string remains, if any?

I know she'll have 11 pieces of string but .06 is left over after you do the work. How would you show that in fraction form and how would you get to it?

A landscaper is designing a flower garden in the shape of a trapezoid. She wants the shorter base to be 3 yards greater than the height and the longer base to be 7 yards greater than the height. She wants the area to be 210 square yards. The situation is modeled by the equation h^2 + 5h = 210. Use the Quadratic Formula to find the height that will give the desired area. Round to the nearest hundredth of a yard.

a.
24.41 yards

b.
430 yards

c.
14.71 yards
