B
You would divide 45 mm/15mm to get 3. Multiply 3 by 27 to get 81 mm.
I would have used graph b. Because it shows the decrease more than graph a.
The red arrows show that the lines are parallel, but using the stuff given you can make an equation.
its hard to explain without drawing but starting from the 60 if you can make a Z you will get alternate angles and that mean that the given equation MUST be equal to 60. So,
8x-4=60
8x=60+4
8x=64
x=64/8
x=8 (is your answer)
hope you understand
From cm to km you divide the number by 100000
So 35,000/100000 = 0.35km
