Anybody wanna me answer these questions ?

for number 4, you just have to add 6 to 5 times more of a number and that equals at least 21. so it would be,

5x + 6 ≥ 21

for number 6 she already has 3 lbs of things in her bag, so you subtact 3 from 18 and get 15 she can carry 15 more pounds, since each book weighs 3 lbs you divide 15 by 3 and get that she can carry 5 more books in her bag.

answer: the answer is 35%

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
