Answer:
7 cards.
Step-by-step explanation:
60-39.5=20.5, that's what he has left if he buys 5 cards.
so, if you buy 2 more cards, that would be 18 dollars so 20.5-18=2.5
5 cards+ 2 cards= 7 cards.
He still hzs 2.5 dollars left
Rewrite the fractions to have a common denominator to find the difference:
2/3 = 4/6
Difference = 4/6-5/6 = -1/6
Sequence formula = an = a1 + d(n-1)
A1 is the first term 5/6
And d = -1/6
Sequence = 5/6 -1/6(n-1)
Simplify to get an =(-n +6)/6
You can tell that a line is parallel if the lines can go on forever without crossing or intersecting. A line is perpendicular when the lines intersect at a right angle. If the slopes are either equal or negative reciprocals, they cannot be parallel or perpendicular.
