Which expression is equivalent to 12x+(−7)−214x−(−2)?

is the equivalent expression

Step-by-step explanation:

Given the following expression

We are expected to find and re-write the expression such that it equals the given expression

We proceed by opening all brackets and work operations on signs

collecting like terms we have

we can further re-write the new expression as

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

multiply each one by 3.14
