5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
8a+48b=
The GCF is 8a.
8a-3b = 5
8a-a-a = 6a
8a - 15 = -3 8a = 15 - 3 8a = 12 a = 12/8 = 6/4 = 3/2
8A + (8A+8) + (8A+16) = 888 24A + 24 = 888 ===> 24A = 864 ===> A = 36 The multiples are 8A, 8A+8, 8A+16 = 288, 296, 304. Sum = 888.
Oh, what a happy little question! To write 8a in algebraic expression, you simply multiply the number 8 by the variable a. This helps us represent the idea of having 8 groups of a in a beautiful and clear way. Just remember, there are no mistakes in algebra, only happy little equations waiting to be solved!
9a - 8a = a
8a/-9=12 8a=12x-9 8a=-108 a=-108/8 a=-13.5 Hence the required answer is -13.5
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3
8a(5a2-1)
