Answer: n=66
Step-by-step explanation:
2n -2 = n + 64 subtract 1n on both sides
- n - n The n’s cancel out
————————
1n - 2 = 64 Add 2 on both sides
+2 +2 The 2’s cancel out
——————-
1n = 66 Divide 1 on both sides
—- ——
1 1 The 1’s cancel out
n= 66
Check it :
2(66) - 2 = 66 + 64
132 - 2 = 130
130 = 130
Given that,
Total no of cards = 20
The ratio of animal cards to fruit cards is 2:3
No of animal cards = 20
Solution,
Let there are 2x animal cards and 3x fruit cards. ATQ,
2x+3x = 20
5x = 20
x = 4
Animal cards = 2x
= 2(4)
= 8
Fruit cards = 3x
= 3(4)
= 12
It is also mentioned that, of the cards, 1/3 have bananas on them. It means,
Hence, 4 cards have bananas on them.
