3x+y = 4
x+y= 2 multiply all the elements of (x+y) by -1 & then add it up to the 1st equation
3x+y=4
-x-y =-2
----------
2x+0y =2 ==> x=2/2 =1 & replace x=1 by its value in any of the equation & you will get the value of y=1
2) 3x+y = 7
x+2y = 4
Follow the same methodology as before, but to eliminate y, multiply the 1st equation by (-2) and you will get x=2 & y=1
Thank you so much, you too.
The formula for the volume of a sphere is (4/3)*pi*r^3. Using this formula, we have 44.6022 cm^3 = (4/3)*pi*r^3. Solving for r, we get 2.2 cm. Thus, the radius of the sphere with an approximate volume of 44.6022 cubic centimeters is 2.2 cm. To add, the volume of a sphere is also exactly two-thirds the volume of its circumscribed cylinder.
The answer is C. 4 to the 3rd power is 4*4*4. 4*4=16 and 16*4=64 so the answer is C.
