Question

Розкрий дужки: 0,2*(5x-15y-2t+3)

Answer 1

Відповідь:

x - 3y - 0,4t + 0,6

Покрокове пояснення:

0,2 * (5x - 15y - 2t + 3) = x - 3y - 0,4t + 0,6

Answer 2

To expand the expression 0.2*(5x - 15y - 2t + 3), you can distribute the 0.2 (or 1/5) to each term inside the parentheses. Here's how you do it:

0.2 * (5x - 15y - 2t + 3)

Step 1: Distribute 0.2 to each term inside the parentheses:

0.2 * 5x = 1x = x 0.2 * (-15y) = -3y 0.2 * (-2t) = -0.4t 0.2 * 3 = 0.6

Step 2: Combine the terms:

x - 3y - 0.4t + 0.6

So the expanded expression is:

x - 3y - 0.4t + 0.6
