Answer:
s=-7/9
Step-by-step explanation:
-9s+12-12=-18s-3-4
-9s=-18s-7
9s=-7
s=-7/9
(if I understood the question correctly)
Step-by-step explanation:
x = 90- 55 = 35
y = 180- x
y= 180 - 35 = 145
z =180- (y +10)
z = 180 - (145 +10)
z = 180-155
z = 25

Answer:
Volume = 10562.96 cu ft
10.56 hr. to drain all the water
Step-by-step explanation:
V = 1/3Bh B = area of the base h = height
The base is a circle, so 
= 10562.96 cu ft
10562.96/1000 = 10.56 hr.
Answer:
No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into -4x-y=-2.
-4x -(-4x + 3) = -2
-4x + 4x - 3 = -2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.
