Answer:
5.625
Step-by-step explanation:
45 ÷ 8 = 5.625
In a geometric sequence dividing any term by the term before it yields the common multiplier.
Then x/(x+8) = (3x-8)/x
Solving for x: reduces to x^2-10x +16 factor into (x-2)(x-8)
Then x = 2 or 8
2 produces a sequence of -2, 2, -2 ...
8 produces a sequence of 4, 8, 16 ...
So, one trillion is 1 and twelve zeros, thus 2.4 trillion is 2 trillions and 400 billions or 24 followed by eleven zeros, because the "4" is using up a space.
now, 1 million is 1 and six zeros, thus 100 millions is 100 and six zeros or 1 and 8 zeros.
now, is 2.4 trillions in four months, thus 2.4trillion/4 will give us how many gallons in 1 month.
to find how many households, simply let's divide it by 100 millions
If $26 represents the cost of the 5 used CDs, than your formula would be "26+4x" ,x being the amount of extra CDs you purchase.
The number CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $26 group.
26+4(6-5)
26+4(1)
26+4
30
6 CDs would cost $30
