Answer:
50 divided by 8 is the best estimation. gives you 6.25
Y = mx + b, where m = slope = rise/run and b, the y intercept value
m = 1/1 = 1, then y = x + b.
We notice that y intercept is = - 1
And the equation is:
y = x - 1
The bus driver arrives in Oban at 11:20
2x+x-7+3x-20=87cm
6x-27=87
6x=114
x=19
Therefore the sides are:12cm, 38cm, and 37cm
15% of 425
(15/100) * 425
(3/20) * 425
(3/4) * 85
255 / 4
63.75
