8r+(12-3)p-7------>8r+9p-7
The denominator is always the number under so in this fraction, we can say 23 is the denominator because it is the number under
To compare these fractions, bring them to the same denominator. Expand the fractions to bring them to the common denominator (LCM):
7/8 = (2 * 7) / (2 * 8) = 14/16
13/16 = (1 * 13) / (1 * 16) = 13/16
Same denominator fractions sorted ascending:
13/16 < 14/16
Initial fractions in ascending order:
13/16 < 7/8
None of the answers are correct because it’s definitely not “Given” because x=20 is like an answer. It’s also not “Distributive Property”, “subtraction Property”, and or “Additional Property” b/c there’s nothing that can be distributed, subtract or add. It’s just an answer.
An hour is 60 minutes.
The trip to the arena + The return drive = 60 mintues.
Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.
The return drive + 8 minutes = The trip to the arena
Let's represent these two equations with variables.
x + r = 60
r + 8 = x
What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.
x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26
Then use r in an earlier equation to find a.
r + 8 = x
26 + 8 = x
x = 34
