Give the values of n and ell for an electron in a 4d orbital. n = ell = 16 select the values of mell and ms that are possible for an electron in a 4d orbital. mell = −4 −3 −2 −1 −1/2 0 +1/2 1 2 3 4 ms = −4 −3 −2 −1 −1/2 0 +1/2 1 2 3 4

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
