Set up a proportion.
5/2 = 1/x
Cross multiply:
2 = 5x
Divide 5 to both sides:
x = 2/5
So 2/5 cups of water are needed for 1 cup of flour.

Step by step Explanation:
Answer:
9.9
Step-by-step explanation:
To solve this problem, we first need to know that the whole length of the circunference is related to a central angle of 2pi radians. Then, we can solve using a rule of three to find the radius:
arc of 6.6 -> central angle of 2/3
arc of 2*pi*r -> central angle of 2pi
2*pi*r * (2/3) = 6.6 * 2*pi
r * (2/3) = 6.6
r = 6.6 / (2/3) = 9.9
So the length of the radius is 9.9
(x-4)² + (x-2)² = x²
(x² - 8x + 16 ) + (x² - 4x + 4) = x
2x² -12x + 20 = x
2x²-12x + 20 - x = 0
2x² - 13x + 20 = 0
(2x-5) (x-4) = 0
2x-5 = 0
2x = 5
x = ⁵/₂
x-4 = 0
x = 4
so x₁ = ⁵/₂ , and x₂ = 4
Answer:
0
Step-by-step explanation:
note that +(- ) is equivalent to -
g(x) + (- g(x)) = g(x) - g(x) = 0
