Which expression is equivalent to -1.3 - (-1.9)−1.3−(−1.9)minus, 1, point, 3, minus, left parenthesis, minus, 1, point, 9, right parenthesis? choose 1 choose 1 (choice a) a -1.3+(-1.9)−1.3+(−1.9)minus, 1, point, 3, plus, left parenthesis, minus, 1, point, 9, right parenthesis (choice b) b -1.3+1.9−1.3+1.9minus, 1, point, 3, plus, 1, point, 9 (choice c) c -1.9+1.3−1.9+1.3minus, 1, point, 9, plus, 1, point, 3 (choice d) d 1.3+1.91.3+1.9

Choise B:

Step-by-step explanation:

For this exercise you must remember the multiplication of signs:

By definition, equivalent expression have the same value.

Then, you can find an equivalent expression to the expression provided in the exercise by simplifying it.

So, given:

To simplify it, you can distribute the negative that is located outside of the parentheses (in order to eliminate the parentheses).

Applying this procedure, you get the following equivalent expression:

Therefore, as you can notice, the expression obtained matches with the one shown in Choice B.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
