6.5 liters per 100 km travelled. 30% of 5 is 1.5, so adding this to the original amount results in 6.5
Find the slope of the line first:
5x - 2y = -6,
y = (5/2)x + 3;
Since we need a line that's perpendicular, m = - (2/5).
The only equation that has the slope of this m is 2x + 5y = -10;
Answer:83 -->17-->103-->43-->7-->1
Have a good day
Y = -7
or
x = 10
or
y = x - 13
there can be endless answers
