Question

greg combined different weights of fertilizer, soil , and compost to make 29 kilograms (kg) of potting soil for some plants. the weight of fertilizer was x kg. the weight of soil was 2 kg more than three times the weight of fertilizer, and the weight of compost was half the weight of fertilizer. this is represented in the equation below: x (3x 2) 1/2x=29 a)3 kg b)6kg c)14kg d)17kg

Answer 1

Let x be the weight of fertilizer. The weight of soil may be expressed as 3x + 2. Lastly, the weight of compost is x/2. The sum of all these weights is equal to 29 kilograms.
x + (3x + 2) + (x/2) = 29

The value of x is 6. Thus, the answer is letter B. 6 kg.
