James studies for his math test for 5/6 of a hour he works on a science project for 1/6 of an hour how much longer does he spend on hes math test then his science project

40 mins longer because 5/6 of a hour is 50 mins and 1/6 of a hour is 10 mins so 50 - 10 = 40

Step-by-step explanation:

it would be:

c.parallelogram.

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
