Math and Arithmetic

b = 1/2 (a - c)

or for a = 3b - 2c: b = 1/3 (a + 2c)

for a= 2bc + d is b= (a-d)/2c

a= 2b +c is c= a - 2b

b=1/3(a-2c)

What is 50.55 round to the nearest hundredth

The metric system is designed to deal in powers of ten, so it has a prefix for 100, which is hecto, but not for 110.

1

c= (a+d) / 2b

We are not told if the car just reaches the deer, or gets to some other distance before or past the deer. If it just reaches the deer, it traveled 90 metres of course. From the information supplied it doesn't matter where the deer was.

To the nearest tenth it is 2796.
