Answer 2

To solve the expressions -1.5(2-4a+20b) and 2.3(3x-4y+5) using the distributive property, you need to distribute the numerical coefficient to each term within the parentheses. Here's how you can do it step by step:

Expression 1: -1.5(2-4a+20b)

Step 1: Distribute -1.5 to each term inside the parentheses: -1.5 * 2 = -3 -1.5 * (-4a) = 6a -1.5 * 20b = -30b

Step 2: Combine the results from Step 1: -3 + 6a - 30b

Expression 2: 2.3(3x-4y+5)

Step 1: Distribute 2.3 to each term inside the parentheses: 2.3 * 3x = 6.9x 2.3 * (-4y) = -9.2y 2.3 * 5 = 11.5

Step 2: Combine the results from Step 1: 6.9x - 9.2y + 11.5

So, the simplified expressions are:

-1.5(2-4a+20b) simplifies to -3 + 6a - 30b. 2.3(3x-4y+5) simplifies to 6.9x - 9.2y + 11.5.
