Which would not be a step in solving 18 = 2(4 + x)? OA. Use the distributive property.
B. Collect like terms.
C. Isolate the variable.
O D. Collect variable terms on one side.

B

Step-by-step explanation:

cuz all the others are right

associative property of multiplication

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
