5B refers to the central notch in the keel of the ship which is the long diagonal piece on the first sheet of wood and 5B refers to the notch in the end of the first bulkhead. This is the piece directly below the keel on sheet one that looks a little like home plate and also contains notches 40,42,46, 47,49,50, 57, slot 6, and tab154.
5b + 5b = 2 x 5b
The GCF is 5b.
2a+5b isn't possible the answer is still 2a+5b.
5b-15 = -10
15 = 5b
5b
5b-32
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
5b + 3 = 10 - 3 - 3 5b = 7 5b/5 7/5 b= 1.5 There you go !
(5b - 4)(5b + 4)
The greatest common factor (GCF) of 15ab and 5b2 is 5b.
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
