Evaluate the determinant to determine whether the equation is true or false. 1 x x 1 y y3 = (y - x)(z - x)(z-7) 1 2 231 evaluate the determinant and the expression on the right side of the equation. (simplify your answers completely.) |1 x 1 y 3 = 1 z 231 (y - x)(z – x)(z- y) = is the equation true or false? true o false

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

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
