Let
y-------> number of books read during the month 
x------> number of picture of a book
we know that

in this problem
for 
calculate y

therefore
the answer is
The number of books read during the month
is 
Figure 4 is the image of the square LMNP after the translation.
<u>Step-by-step explanation:</u>
Let us see the coordinates of the pre image LMNP as,
L (-3,1)
M(-1,1)
N(-1,-1)
P(-3,-1)
after translation of (x,y) → (x+5, y -3) the coordinates of the image obtained as,
L'(2,-2)
M'(4,-2)
N'(4,-4)
P'(2,-4) which matches the image 4.
By right triangle trigonometry, the sine of the measure of an angle is the ratio of the opposite side of this angle to the hypotenuse.
Thus,


is a constant which can be found using a calculator:
with calc in pc: view → scientific → 27→sin = 0.45399,
thus x=34/0.45399=74.89
Answer: 74.89
It all depends where you start from, and what route you take.
For me, if I take the shortest possible route, then it's 3,956 miles to London
and 9,809 miles to Jakarta. So for me, Jakarta is 5,853 miles farther.
But if you're starting from, say, Singapore, then London is 6,192 miles
farther away than Jakarta.
