15 units use socratic

step-by-step explanation: 15 units

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

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

so, converting firstly the mixed fractions to improper fractions and then "adding".

he has now walked a total of what?

if i know what this is maybe i can
