Jolly plants 4 cucumber seeds. She has 10 cucumber seeds left. How many seeds did she have before she planted the 4 cucumber seeds?

Let x represent the number of original cucumber seeds. If Jolly planted 4 seeds, then x-4= the number of remaining seeds (10). So x-4=10. Solve for x. Add 4 to each side of the equation. The solution is x=14. Jolly started out with 14 cucumber seeds.

The Green's family gravel driveway is 40 yards long. They would like to pave one-fourth of the driveway. How may feet like they like to pave?

The driveway is 40 yards long. Convert 40 yards to feet. One yard equals three feet, so 40 yards = 40 x 3 = 120 feet. To determine one-fourth of 120 feet, divide 120 by 4. 120 feet divided by 4 = 30. The Green family would like to pave 30 feet of their driveway.
