Question

-0,5×(2a+0,4y-7,6x)=?

Answer 1

-0,5*2а-0,5*0,4у-0,5(-7,6х)
-а-0,2у+3,8х

Answer 2

To simplify the expression -0.5 × (2a + 0.4y - 7.6x), we can distribute the -0.5 to each term inside the parentheses.

-0.5 × 2a = -1a = -a -0.5 × 0.4y = -0.2y -0.5 × -7.6x = 3.8x

Putting it all together, we have: -0.5 × (2a + 0.4y - 7.6x) = -a - 0.2y + 3.8x

Therefore, the simplified expression is -a - 0.2y + 3.8x.
