Answer:
x = -1
Step-by-step explanation:
Let the mystery number be x
Equation:
60 - 4x = 8x + 72
Subtract 60 from both sides
-4x = 8x + 12
Subtract 8x from both sides
-12x = 12
x = -1

1/3x=−20
X is 1/3
X times 3 = a full X
Fill it in
X times -20 = -60

Answer:
1/2 = 0.5
Step-by-step explanation:
The given fraction is:
1/2
By simple calculation, we can convert the fraction into decimal
Division will give us 0.5
As the decimal form has only one digit after the point so there is no need to round off.
Hence, 1/2 in decimal form is 0.5 ..
The slope will be the same, so we know the equation will be y=-2x+b. But there is a different b.
For x=4, y will be 1 because the point (4,1) is given.
So 1=-2*4 + b => b = 9
So the equation of our parallel line is y=-2x+9
If we subtract 1 from both sides, we get y-1 = -2x + 8
Then factor out -2 on the right hand side: y-1 = -2(x - 4)
That's answer A!
