ANSWER: 12,345,678
EXPLANATION:
we can work backwards by figuring out what 9(the answer) is multiplied by to get 111,111,102 (the starting number) we can do this by dividing by 9:
111,111,102/9 = 12,345,678
so: 9 * 12,345,678 = 111,111,102
which also means
111,111,102/12,345,678 = 9 (with 0 as a remainder)
A - 4b = 10 . . . . . (1)
a = b - 2 . . . . . . (2)
putting (2) into (1), gives:
b - 2 - 4b = 10
-3b = 10 + 2 = 12
b = 12/-3 = -4
From (2), a = -4 - 2 = -6
Therefore, solution is (-6, -4)
Answer:
Step-by-step explanation:
3 is the power of whole expression.
so,
that can be expressed as
64 = 2(l+w)
64 = 2[l+(4)]
64 = 2l + 8
64 - 8 = 2l
56 = 2l
56/2 = 2l/2
28 = l
