Form a sequence that has two arithmetic means between -1 and 59. a. -1, 29, 29, 59 b. -1, 19, 39, 59 c. 19, -1, 59, 39 d. -1, 14, 29, 44, 59 select the best answer from the choices provided a) a b) b c) c d) d

Correct choice is B

Step-by-step explanation:

For the numbers -1 and 59, find the difference 59-(-1):

since 59-(-1)=60 and (two arithmetic means tells you there will be three intervals), two arithmetic means will be

The only correct sequence is -1, 19, 39, 59.

answer: i guess 105 degrees?

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
