Thomas and Freya have ages that are consecutive integers. The sum of their ages is 16 less than three times the larger of the two ages. Which equation could be used to solve for the smaller age, a? 1. a+(a +1) = 3(a+1) - 16
2. a + (a+2) = (3a + 1) - 16
3. a(a + 1) = 16 - 3a
4. a(a + 2) = 16 - 3(a +2)

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

answer: you need to organize this better it does not make sense.
