each side of the equation has to balance, so basically, we add 4.7 to each side of that equation

Answer 31

pls hurry

Answer 32

@BPDlkeme234 do you know the answer???

Answer 33

well he lost 1.8 in the first week, gained 0.9 in the second week, lost 1.4 in the third week and gained 0.4 in the fourth week.

so: (-1.8)+ (-0.9)+(-1.4) +(+0.4) = (-1.8) +(-1.4)+ (+0.9)+ (+0.4)= ((-3.2) +(+1.3)
so overall he lost 3.2 and gained 1.3 = 1.3 - 3.2 = -1.9
i.e total loss of 1.9

Answer 34

–1.8 +0.9 –1.4 +0.4 =? just evaluate this and you'll get it

Answer 35

i would get -1.9

Answer 36

i.e the negative sign means he lost 1.9

Answer 37

so it would be B then right

Answer 38

correct answer = B
