How do you solve, 3r+2(12r+7)less then or equal to 5r-8

r  ≤ -1

Step-by-step explanation:

Given in the question

3r + 2(12r)  + 2(7) ≤ 5r - 8

3r + 24r + 14 ≤ 5r - 8

27r + 14 ≤ 5r - 8

27r - 5r +14 + 8 ≤ 0

22r + 22  ≤ 0

22r ≤ -22

Move term containing r to the left, all term to the right.

r  ≤ -22/22

simplifying

r  ≤ -1

all negative integers which are smaller than or equal to -1

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12
