1/2(-3/5x+1)+7/4=31/12+1/5x. solve for x.

Multiply everything by 12 * 5 if you want to get rid of fractions - it's not needed, but i do prefer dealing with integers. Regardless of that previous step, you distribute the first group (1/2 * -3/5x + 1/2 * 1). Then separate x to one side of the equal sign, everything else to the other side.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
