2,600/4 =650
650•5 =3,250
I found the unit rate of the 2,600 by dividing the per hour and then times it by the 5 hours
Hopefully that was what you were looking for
The first one is 11 and -11 because when you square them they both get 121
The second one is -7 and -1
Z=72, i was working on it and that’s what i got
I dont know if those lines were suppose to be there, but i put 0.63 in simplest form = 63/100
