7b divide by 12 will equal 4.2 if b = 7.2
To convert inches to feet just divide by 12 (since there are 12 inches per foot) -42 / 12 = 3 feet 6 inches
b^2 - 7b + 12 = b^2 - 4b - 3b + 12 = b(b -4) -3(b - 4) = (b - 3)(b - 4)
Divide 42 by 2 to give you 21.
42
-44
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42

12, 2, 11, 4, and 1
42 Just take 350% and multiply it by 12: 3.5 x 12 = 42
If you divide 42 by 6, you get 7. If you divide 72 by 6, you get 12. 7 over 12 cannot be simplified any further so your answer is 7/12
Divide both halves by 6: 12 : 42 = (12 ÷ 6) : (42 ÷ 6) = 2 : 7 The ratios 12 to 42 is equivalent to 2 to 7.
Question 24/42 divide both by 2 = 12/21 divide both by 3 = 4/7 Check (2x3x4) = 24 / (2x3x7) = 42 Answer 4/7
-12
To convert inches to feet just divide by 12 (since there are 12 inches per foot) -42 / 12 = 3 feet 6 inches
2:7::12:x Divide the '12' by '2' and multiply by '7' Hence 12 x 7 / 2 6 x 7 = 42 Hence 2:7::12:42
42 will not divide evenly into 72. You an divide 42 into 72 but there will be a fraction.
