Answer:
study DUHHHH
Step-by-step explanation:
<span>x − y + 2z = 1
3x + y + 5z = 19
2x − y − 2z = −17
-3x+3y-6z=-3
</span>3x + y + 5z = 19
4y-z=16 (1)
-2x+2y-4z=-2
<span>2x − y − 2z = −17
y-6z=-19 (2)
</span>4y-z=16 (1)
y-6z=-19 (2)
4y-z=16
-4y+24z=76
23z=92
z=4
y-6z=-19
y-6×4=-19
y-24=-19
y=24-19
y=5
<span>x − y + 2z = 1
</span>x-5+2×4=1
x-5+8=1
x+3=1
x=-2
(x,y,z)=(-2,5,4)
Square foot tiles means that they are 1 x 1 foot tiles
you are given that the room is 7 x 6 feet
that is the area is 42 ft^2
A tile is 1ft^2
so you will need 42 tiles for the room
D.) 42 tiles
Hope this helps
