Answer:
7/6 or 1 1/6
Step-by-step explanation: you multiply 2 into 1/3 and 1/4 and get 2/3 and 2/4. You add 2/3 and 2/4 using lowest common denominator and get 14/12. Simplify 14/12 and get 7/6 or 1 1/6
1. 12*100 - 12*5
You would use the distributive property to get this equation (it is equivalent to the original one)
2. Um... There's no actual story for this problem; sorry I can't solve this problem
Answer:
the formula for the volume of a sphere is

r is the radius, which is half the diameter. Since the diameter of the whole sphere is 18 the radius would be half of that, which is 9. If you plug 9 into the formula you get 3052.08in.cubed. Now you must find the volume of the smaller core, the diameter of the core is 3, so the radius is 1.5 and if you plug that into the formula you get 14.13in.cubed. Since you're finding only the volume of the outside layer, you would subtract the volume of the core from the whole sphere, so 3052.08-14.13=3037.95
Your answer is 3037.95in.cubed
Answer:
C. -8x + 10
Step-by-step explanation:
-2(3x + x - 5)
Combine like terms
= -2(4x - 5)
Distributive property
= -8x + 10
