Substituting x = 3 into the first expression:
-4(3) - 8 = -12 - 8 = -20
Substituting x = 3 into the second expression:
-2(3 + 1) - 2(3 + 3) = -2(4) - 2(6) = -8 - 12 = -20
Meat =35/100
vegetables =15/100
sauce =5/100
bread =5/100
There were 40 tourist class passengers and 12 first class passengers.
Explanation:
Let the number of passengers who booked for tourist class be
=
x
Then, number of passengers who booked for first class
=

Hence verified.
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.
