Answer:
It's (C) But if you do it like this you get 13/6
Step-by-step explanation:
2/3x = 3.5 + 3/8x
8 • (2/3x) = 3.5 + 3 • (3/8)
16/24 X = 3.5 + 9/24 X
16/24x - 9/24x = 3.5
7/24 X = 3.5
7x/24 = 3.5
24 • (7x/24) = 3.5 • 24
7x = 84
7x/7 = 84/7
X = 12.
The number is 12.
Let First Sphere be the Original Sphere
its Radius be : r
We know that Surface Area of the Sphere is : 4π × (radius)²
⇒ Surface Area of the Original Sphere = 4πr²
Given : The Radius of Original Sphere is Doubled
Let the Sphere whose Radius is Doubled be New Sphere
⇒ Surface of the New Sphere = 4π × (2r)² = 4π × 4 × r²
But we know that : 4πr² is the Surface Area of Original Sphere
⇒ Surface of the New Sphere = 4 × Original Sphere
⇒ If the Radius the Sphere is Doubled, the Surface Area would be enlarged by factor : 4
Answer:
13 =w
Step-by-step explanation:
-33 = 6 - 3w
Subtract 6 from each side
-33-6 = 6 - 3w-6
-39 = -3w
Divide each side by -3
-39/-3 = -3w/-3
13 =w
