First, let's convert the mixed fraction into an improper fraction:
2 3/8 = 21/8
21/8 * 400 = 8400/8
8400/8 = 1050
It will cover 1050 square ft.
Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
-4x + y = 0
+4x +4x
y=4x
-5x - 2y = 13
+5x +5x
-2y = 5x+13
-2(4x) = 5x+13
-8x=5x+13
-5x -5x
-13x/-13=13/-13
x=-1
Thus:
y=4x
y=4(-1)
y=-4

Answer:
z = -5
Step-by-step explanation:
add 9z to both side giving you ---> 18z+93 = 3
