Let, the number = x
So, x * 1/10 = 0.04
x = 0.04 * 10
x = 0.4
So, your final answer is 0.4
Hope this helps!
X= - 4/5
Answer for number 10
Answer:
Step-by-step explanation:
Review the standard equation of a circle with center at (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
A point on (4, -2) has the radius r^2 = (4)^2 + (-2)^2, or r^2 = 20, or r = 2√5. Knowing the center is at (0, 0), we can write:
x^2 + y^2 = 20, or x^2 + y^2 = (2√5)^2

Answer:
It might help you if you knew what variable was.
A variable can be (x) or (y) or anything really it just a letter the represents a number.
In this case, when it says solve for a variable it means find what the variable equals. For example:
4x + 18 = 2
here you need to find the value of X.
x = -5
X equals negative 5 because you multiply the variable to the number:
4 x -5 = -20
-20 + 18 = 2
making the answer:
4(-5) + 18 = 2
x = -5
