Find the area of the room by multiplying the length by the width:
Area of room = 15.5 x 18.5 = 286.75 square feet.
Divide the total area of the room by the area of a box to find the number of boxes needed.
286.75 / 25 = 11.47
Since you can't buy a partial box, round up to the nearest whole number.
You need B. 12 boxes total.
Answer:
x=18
Step-by-step explanation:
S=(n-2)180
S=(5-2)180
S=3x180
S=540
540=(9x-6)+(3x+23)+95+((7x-4)+90
540=19x+198
540-198=19x
342=19x
342/19=x
x=18
Answer:
you have to add them all together to get the right answer.
Step-by-step explanation:
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=

(divided both sides by -3z)
z=
