Using google translate: When photocopying a credential, it is first enlarged to triple and subsequently the resulting copy is halved. What is the final effect on the original credential? If the credentials is a rectangle of 10 by 6 cm. What area will you have in the first photocopy? And in the second?
Original: 10 by 6 cm ; Area = length * width = 10 x 6 = 60 cm²
first copy: enlarged to triple 10 x 3 = 30 6 x 3 = 18 30 x 18 = 540 cm²
second copy: halved 30 x 1/2 = 15 18 x 1/2 = 9 15 x 9 = 135 cm²
7: $200<3x-y(28) where x represents each kids money out of it and y represents the parents pay. 8: 7.00>(is greater then or equal to) 0.75X + 1.29Y where X is the amount of bagels and Y is the amount of cream cheese containers. 9: $25 + $75>4X where X is the shirts 10: 720-120>(greater then or equal to) 32X where X is the number of people in each row 11: 2400= 2100+ X(1/20) where X is the value of all things sold. 12: 2000<(X7)-668 where X is the amount of cans in one day. 13: 100> 7X - 10Y where X equals the amount of months and Y equals the amount of CD's 14: $80 - $22> (greater than or equal to) 17X where x equals the amount of shirts.
first off sorry it took so long to answer, these long word questions are time consuming and i havent done them in a while so i had to refresh my memory, secondly the equations all end where i say the word "where", thirdly i am absolutely sure of all these answers except for the first one, the first one i am pretty sure i still got it but not 100%.
