How do you attack this problem:
"Apples are collected in a basket for 6 people. One-third, one-fourth, one-eighth, and one-fifth are given to four people, respectively. The fifth person gets tens apples with one apple remaining for the sixth person. Find the original number of apples in the basket." I came up with 1/3x + 1/4x + 1/8x + 1/5x + 11 = x. After using the least common denominator of 120, adding them up to 109/120x, I had: 109/120x + 11 = x. Then I subtracted 109/120x from x, which resulted in 11/120x. Then I multiplied by 120/11 on both sides, and ended up with x = 1320/121, or 10.90 repeating. This is wrong, as the answer is 120. How do I do this problem? ---- Also, if you have a triangle, and the base is 4 inches, one side is 3 inches, one side is 2 inches, and x represents half the height, and the area is 2.9047 inches squared, how do you find X? The answer is ~.65 inches, but using the formula for the area of a triangle, A = 1/2 X b X h, I get: 2.9047 = 1/2 X 4 x 2x, as 2x equals the height. Which equals: 2.9047 = 2 X 2x, 2.9047 = 4x, and then 2.9047/4 = ~.726. However, x does not equal ~.726, but ~.65.
