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:
\[
0.70 \cdot xx
\]
