Answer:
D. y=2x(4×2)
Step-by-step explanation:
y=8 and x=4 and they are asking about the books that Maggie read how they the books re equal to the ones Rahul read. so y will be equal to x times 2 which is also x+x.
Hope I helped!
How to you write the number 5,000,000,000,000,000,000,000,000,000,000
tresset_1 [31]
The way you wrote it is how you write it unless you want to do scientific notation then the answer would be, 5x10^30 because for it to be in scientific notation it has to be between 10 and 1 so I moved the decimal spot over 30 to get it into scientific notation. Hope this helps out.

Answer:
6 years
Step-by-step explanation:
The shorter tree is 4 ft shorter, but is growing faster. It is making up that difference at the rate of 24-16 = 8 inches = 2/3 ft per year. It will take ...
(4 ft)/(2/3 ft/year) = 4·(3/2) years = 6 years
for the two trees to become the same height.
_____
If you like, you can write an equation for the height of each tree (in feet or inches) and then solve for the time (t, in years) when the two equations give equal values.
In feet, we have
A height = 8 + (16/12)t
B height = 4 + (24/12)t
These will be equal when ...
8 + (16/12)t = 4 + (24/12)t
4 + (16/12)t = (24/12)t . . . . . . . subtract 4
4 = (8/12)t . . . . . . . . . . . . . . . . .subtract 16/12·t
4·(12/8) = t . . . . . . . . . . . . . . . . multiply by the inverse of the coefficient of t*
6 = t . . . . . . . . . the trees will be the same height in 6 years
_____
* This is 4·(3/2), which should look very much like the answer we got at the beginning. Note that this is the initial difference in height divided by the difference in growth rates. Multiplying by the inverse of a number is the same as dividing by the number.
