1/2x=-5
In the standard equation for an ellipse, b is half the length of the _____ axis.Answer:
Multiply by 1/2 or Divide by 2
The Chinese use a method called "multiplication grid" or "Chinese lattice multiplication". It involves creating a grid and filling it in with the digits of the multiplicand and multiplier, then multiplying each digit and summing the results diagonally to get the final product. This method is a visual and systematic way to break down and solve multiplication problems.
We write .5 or 0.5 as the decimal for one half.
As an equation: 24 = x/2
1/2x=-5
3.5
X ÷ 2 = 14 or X/2 = 14 where the / means divided by.
Division by a number is the same as multiplication by its reciprocal (or inverse). So, division by a half is the same as multiplication by 1/half or two. Thus, the answer is 432 / (1/2) = 432*2 = 864
In the standard equation for an ellipse, b is half the length of the _____ axis.Answer:
To balance a redox equation using the oxidation number method, assign oxidation numbers to each element in the reactants and products, identify the elements undergoing oxidation and reduction, write half-reactions for oxidation and reduction, balance the atoms in each half-reaction, balance the charges by adding electrons, multiply the half-reactions to make the electrons cancel out, and then add the balanced half-reactions to obtain the overall balanced redox equation.

The half equation for the reduction of copper oxide by carbon is: CuO + C -> Cu + CO
Yes, an isotope is still radioactive after one half life. There is simple one half of it left. And there will be one half of that half, i.e. one quarter left after a second half life, and half of that half, i.e. one eight left after a third half life, etc. The equation for half-life is ... AT = A0 2(-T/H) ... where A0 is the starting activity, AT is the ending activity at some time T, and H is the half-life in units of T. Sometimes, you see this equation in other forms, such as with e instead of 2, but there is another factor in the exponent. They are all the same. This equation, with the 2, makes the meaning of half-life clear because a negative power of 2 is simply 1/2, 1/4, 1/8, etc.
No, it cannot. The product of a rational and irrational is always irrational. And half a number is equivalent to multiplication by 0.5
