Standard form is
ax+by=c
get all x and y on one side
first distribute
-1(x-y)=-x+y
now weh have
8-x+y=-3x+5
add 3x to both sides
8+2x+y=5
minus 8 from both sides
2x+y=-3
You divide 2.5 to both the miles and hours to get 1 hour and the miles remain.
The answer is 54 miles
1) 16x16= 256ft
16x3x4= 192ft
add them together
256+192= 448ft2 (2 is the little number at the top next to the unit)
2) 3.14x7(2)= 153.86ft2
and i’m not sure on the other part SORRY
