If x and y are positive integers, what is the value of xy ? (1) The greatest common factor of x and y is 10. (2) The least common multiple of x and y is 180.

The value of xy = 1800

Step-by-step explanation:

The product of x and y can be found by using the formula,

Greatest common factor of x and y × least common multiple of x and y

That is,

GCD of x & y multiplied by LCM of x & y we will get xy.

xy = 10 × 180 = 1800

Thus we can conclude the value of xy = 1800

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
