Step-by-step explanation: 2 - (-5) = 7, 2- (-5) is the same thing as 2 + 5, think the two subtraction signs with the left parentheses as a plus sign +, (looks like one doesn't it?) so 2+5=7.

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
