How do you subtract an integer from another integer without using a number line or counters? give an example.

Step-by-step explanation:

Additive inverse is the opposite of a number; the sum of additive inverses is zero. An integer and its additive inverse make up a zero pair.

example: 3

integer: -3+3=0

additive inverse: 3-3=0

Hope this helps!

Thanks!

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!
