Hey there! :)
The formula for finding volume of a sphere = 4/3 · π · r³
Radius = 1
1³ = 1 × 1 × 1 = 1
π = 3
3 × 1 = 3
3 × 4/3 = 12/3 = 4
The volume is 4 in³
Hope this helps :)
Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer: $8 chicken $5 duck
Step-by-step explanation:
50x+30y=550
x=8
y=5
400+150=550
Step-by-step explanation:
9x^3+6x^2-3x
Cannot be simplified because there are no like terms but can be factored as
=3x(3x−1)(x+1)
