If a + b = 6, what is the value of 3a + 3b?
A = 3B = 5 ___________ 2 ( 3A + B) = 2 (9 + 5) = 2 (14) = 28
(3b)5 = 243 b5The actual numerical value depends on the value of ' b ',and it changes instantly any time ' b ' changes.
3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4
the answer is 11. b = 11 b is unknown value. We need to find out what is "b" to make the statement true. write the given statement 3b + 15 = 48 Subtract 15 from both sides 3b + 15 -15 = 48 - 15 3b = 33 Divide both sides by 3 3b/3 = 33/3 b = 11
