Students are paired in teams for a group science project. The number of hours each student spends working on the group project are recorded on the bar
chart below. If Paloma and Abdul are a team, and Ben and Min are a team,
how many more hours did Paloma and Abdul spend working on the project
combined than Ben and Min?

They spent 4 more hours.

Step-by-step explanation:

I added up Paloma's hours and Abdul's, 21 + 18 = 39! And then I added Ben's and Min's, 13 + 22 = 35! So then I subtract 39 - 35 = 4! yay!

If I got it right can I have Brainliest thanks!

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

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
