Answer: 5</h3>
Work Shown:
g = number of hours that Gary exercises
3g-2 = number of hours that Jessica exercises
(g) + (3g-2) = 18
4g-2 = 18
4g = 18+2
4g = 20
g = 20/4
g = 5
Gary exercises 5 hours per week.
Answer:
2500 is not a reasonable estimate.
Step-by-step explanation:
We are given the following in the question:
Number of pages read by Josie = 246
Pages read by older brother = 3 to 4 times as many pages as Josie
If x represents the number of pages read by her brother, we can write:

Putting values, we get,

Since, 2500 does not lie in this interval

Thus, 2500 is not a reasonable estimate for the number of pages that Josie's brother read.
Adding 15 to both sides. In order to get it to the opposite side of the equal sign, you must do its opposite. You can't add 8x to both sides, because the opposite of positive 8x is negative 8x and that's not what they're asking. The opposite of negative 15 is positive 15, so it works. Opposite of positive 3 is negative three, and they're wanting a positive, so it will not work. Adding 2x wouldn't work, because it's already positive..
