POSSIE A new vegetable fertilizer will be tested at two different
levels (regular concentration and double concentration). The
experiment design includes two treatment groups and will be
completed on 40 farm plots. Half of these farm plots are
regularly in the shade.
Based on the information above, which of the following
would be the best blocking method?

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

the answer would be 44.79
