Question

Can someone plz help me?​

Answer 1

b = 23.1

Explanation:

25+(11/12)b=47

25+11b/12 = 47

11b/12=47-25

11b/12 = 22

cross multiply over the bracket

11b = 22 × 12

11b = 34

divide by 11

11b/11 = 34/11

b = 23.09

b = 23.1 approximately

Answer 2

Answer: b = 24

Work Shown:

25 + (11/12)b = 47

25 + (11/12)b-25 = 47-25 ... subtract 25 from both sides

(11/12)b = 22

12*(11/12)b = 12*22 ... multiply both sides by 12

11b = 264

11b/11 = 264/11 .... divide both sides by 11

b = 24
