Answer:
y=42-x
x=42-y
Step-by-step explanation:
x=42-y
Subtract y from both sides of the equation
y=42-x
Subtract x from both sides of the equation
Answer:
lesser x = -6
greater x = 12
Step-by-step explanation:
(x - 3)^2 - 81 = 0
(x - 3)^2 = 81
x - 3 = +/- 9
x - 3 = 9 or x - 3 = -9
x = 12 or x = -6
Answer:
126 centimeters squared
Step-by-step explanation:
To solve the set of equations given above, we can use the substitution method where we substitute one equation to the other and solving for one variable. We do as follows:
<span>0.4x - 0.1y = 2
x = 5 + 0.25y
0.2x + 0.5y = 1
</span>0.2(5 + 0.25y)+ 0.5y = 1
y = 0
x = 5
Therefore, the correct answer from the choices is option A, (5,0).
1758.4 yards because you multiply 280 by two and by pi
