Write an expression that is equivalent to 2.5x + ( 5y) -2.5

2.5(x + 2y - 1).

Step-by-step explanation:

2.5x + ( 5y) -2.5

2.5x + 5y - 2.5  (we can just remove the parentheses without changing the value of the expression)

Each coefficient is divisible by 2.5 so by the distributive law:

2.5x + 5y - 2.5

= 2.5(x + 2y - 1).

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.
