As in decimal it would be 0.4 but if you want a fraction it could be 4/10
160 is the first because 1 inches 20 but it says 2 inches so at 40+40+40+40
and the 2nd part is yes he is correct because he converted the inches into feet so i think he is also correct
-9 (5m+2) = 0
-45m - 18 = 0
+18 +18
-45m = 18
-45m/-45 = 18/-45
m= 0.4
3a - 1 = 12
+1 +1
—————-
3a = 13
—- ——
3 3
—————
A=4 1/3
Here you go . 146 is the answer with the work shown.
