Question

0.4(7х-2)-1.6+1.7х упростите выражение

Answer 1

0,4*(7х-2)-1,6+1,7х= 2,8х-0,8-1,6+1,7х= 4,5х-2,4

Answer 2

2,8х-0,8-1,6+1,7х

4,5х-2,4

Answer 3

To simplify the expression, follow these steps:

1. Distribute the 0.4 across the terms inside the parentheses.
2. Combine like terms.

Let's proceed with the simplification:

0.4(7x - 2) - 1.6 + 1.7x

Step 1: Distribute the 0.4

0.4 * 7x = 2.8x 0.4 * (-2) = -0.8

The expression becomes:

2.8x - 0.8 - 1.6 + 1.7x

Step 2: Combine like terms

Combine the x terms (2.8x and 1.7x) by adding their coefficients:

2.8x + 1.7x = 4.5x

Now, combine the constant terms (-0.8 and -1.6) by adding them:

-0.8 - 1.6 = -2.4

The fully simplified expression is:

4.5x - 2.4
