NEED HELP SOON! Which equations have the variable term isolated to one side of the equals sign, and the constant isolated to the other side, for the equation 1 5 x + 1 3 = −1 2 x + 8 3 ? Select all that apply. One-fifth x minus StartFraction 7 Over 3 EndFraction = negative one-half StartFraction 7 Over 10 EndFraction x = StartFraction 7 Over 3 EndFraction Negative StartFraction 7 Over 3 EndFraction = Negative StartFraction 7 Over 10 EndFraction x x = negative five-halves x + StartFraction 35 Over 3 EndFraction 0 = negative StartFraction 7 Over 10 EndFraction x + StartFraction 7 Over 3 EndFraction

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
