The value of xx is decreased by 30, percent30%. Which expression represents this situation

Answer 1

If \( xx \) is decreased by 30%, you can represent this mathematically as follows:

1. Determine 30% of \( xx \), which is \( 0.30 \cdot xx \).
2. To decrease \( xx \) by this amount, you subtract it from \( xx \):

\[ xx - (0.30 \cdot xx) \]

3. This can be simplified further:

\[ xx(1 - 0.30) = xx(0.70) \]

So the expression that represents the value of \( xx \) decreased by 30% is:

\[ 0.70 \cdot xx \]
