The answer would be 21 because its the same length as the other side.
5(n + 27) >= 6(n + 26)
5n + 135 >= 6n + 156
-n >= 21
n <= -21
Answer:
3 pairs for the price of two.
Step-by-step explanation:
$10 per pair
then:
3 pairs costs $20
20/3 = $6.6667 each pair
- Buy one and get 25% of the second
25% = 25/100 = 0.25
then:
first pair $10
second pair: 10 - (10*0.25) = 10 - 2.5 = $7.5
first + second pair = 10 + 7.5 = 17.5
2 pairs costs $17.5
17.5/2 = $8.75 each pair
then:
the best deal:
3 pairs for the price of two.
