1)Each packet must have at least 20 gold stars = x > or equal to 20
2)Each packet must have at least 15 silver stars = y > or equal to 15, is this correct?
3)The total number of stars in each packet must not be more than 60 = x+y < or equal to 60, is this correct?
4)x < 2y, two y is less than equal to x, is this right?
1) yes
2) yes
3) yes
4) If x<2y, then that would mean that 2y>x. So 2y is greater than x. There is no "or equal" sign in the original equation.
Let's go through each statement and determine if they are correct:
1) "Each packet must have at least 20 gold stars = x ≥ 20." This statement is correct. It means that the variable x, which represents the number of gold stars in a packet, should be greater than or equal to 20.
2) "Each packet must have at least 15 silver stars = y ≥ 15." This statement is also correct. It means that the variable y, which represents the number of silver stars in a packet, should be greater than or equal to 15.
3) "The total number of stars in each packet must not be more than 60 = x + y ≤ 60." This statement is correct. It expresses that the sum of x and y, representing the gold and silver stars in a packet respectively, should be less than or equal to 60.
4) "x < 2y, two y is less than or equal to x." This statement is not correct. It should be written as "2y ≤ x," meaning that twice the value of y should be less than or equal to x.
In summary, Statements 1, 2, and 3 are correct, but Statement 4 needs to be adjusted.
