Which expression is equivalent to −2.6+(−2.9)+(−7.1) ?

-12.6

Step-by-step explanation:

To evaluate the given expression

-2.6+(−2.9)+(−7.1, first we will open out the brackets and multiply the signs. Before that, we must take note of the following sign operations

-×- = +

-×+ = -

+×- = -

+×+ = +

The equation above becomes;

-2.6-2.9-7.1 (all the signs are now minus since the product of plus and minus sign gives a minus sign)

(-2.6-2.9)-7.1

= -5.5-7.1

= -12.6

Since all the values in the equation are negative values, our resulting answer will be a negative value.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

c - they will have the same distribution
