A=4-3b
subtract 4 from both sides
a-4=-3b
divide by -3 for both sides
(a-4)/-3 = b
Calculate first the common difference of the arithmetic sequence,
d = (-29 - -4)/(8 - 3) = -5
The first term is calculated through the way below,
a1 = -4 + 5 + 5 = 6
Thus, the first term of the arithmetic sequence is 6 and the common difference is -5.
You multiply 523x12 by writing it out. 523x12 is equal too 6,276
It's the same because it's used the commutative property where:
a+b = b+a
So, 86+68+38=192 it's the same sum as 68+38+86=192
