A system of equations is given below: y = 3x + 4
2x + 3y = 10
Which of the following steps could be used to solve by substitution?
оа
3x + 4 = 2x + 3y
Ob
2x + 3(3x + 4) = 10
Oc
2(3x + 4) + 3y = 10
Od
3(y = 3x + 4)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

it will be a cylinder. with a diameter of 8 and 4 single pieces high
