Circle the statements below that are true for all values of x, y, and z. For any statement that is not always true, give an example of values of x, y, and z for which the statement is not true. (a) x(yz) = (xy)z. (b) x ÷ (y ÷ z) = (x ÷ y) ÷ z. (c) x + (y + z) = (x + y) + z. (d) x − (y − z) = (x − y) − z. Who ever answers will be giving brainlist

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
