-7+2 adding and subtracting integers

Step-by-step explanation:

-7 + 2 = -5

-7 + 2 = -5

Explanation:

All you need to do is to think about it like regular math. The lower the negative number is, the smaller it is. If we do addition we're adding to the number so (+2) just makes it 2 higher. So we get -5.

Hope this helps and have a nice day!

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

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.
