To use the distributive property and write an equivalent expression to -7.5(10 - 4q + 6), we would distribute -7.5 to each term inside the parentheses.
Starting with the expression -7.5(10 - 4q + 6), we can distribute -7.5 as follows:
-7.5 * 10 + (-7.5) * (-4q) + (-7.5) * 6
This simplifies to:
-75 + 30q - 45
Combining like terms, we get:
30q - 120.5
Therefore, an equivalent expression to -7.5(10 - 4q + 6) is 30q - 120.5.
