I believe it would be .21m. So for example.The memory stick is sold normally for $14, so to plug it into the equation it would be: .21(14), which gives you the discount of $2.94. Subtract that amount from the original price, and that gives you the sale price. .21(14)=2.94 14-2.94=11.06~~~~~Sale price
Dang I was just about to say 22
Answer:
1500
Step-by-step explanation:
Given that :
Total number of marbles held by Layala and Zahra = 2700
Ratio = 2 : 7
Layala's share of marbles : (2 / (2+7)) * 2700
= 2/9 * 2700
= 600
Zahra's share of marble : (7 / (2+ 7)) * 2700
= 7 / 9 * 2700
= 2100
Hence, Zahra must have given away (2100 - x) = 600
2100 - 600
= 1500 marbles, so that both Zahra and Layala have the same number of marbles
Answer:
4 is the square root of 16, so if it has to be negative, -4 would be the answer. Because you can't find the square root of -16. It could also be +-4 because the square root of -16 is invalid. Hope this helped.
