A car runs 9 km using 1 litre of petrol. How much distance will it cover in 3(2/3) litres of petrol?​

distance covered in 1 litre=9 km

distance covered in 3 2/3 litres=?

           distance                    litres

                     9                      1

                     ?                    3 2/3=11/3

=11/3 * 9

=99/3

=33 km will be covered in 11/3 litres of petrol.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
