What is the answer for 0.8*-23+0.8*-7 with step by step

Answer 1

The expression 0.8*-23+0.8*-7 is evaluated by multiplying 0.8 with -23 and 0.8 with -7 separately, then adding both products to arrive at the final answer of -24.

Step-by-step explanation:

The question asks us to calculate the expression 0.8*-23+0.8*-7. To solve this, we will perform each multiplication separately and then add the results:

1. Multiply 0.8 by -23 to get -18.4.
2. Multiply 0.8 by -7 to get -5.6.
3. Add the results of the two multiplications: -18.4 + (-5.6).
4. Adding a negative number is the same as subtracting its positive equivalent, so the calculation becomes -18.4 - 5.6.
5. When we subtract 5.6 from -18.4, we get -24.

Therefore, the final answer to 0.8*-23+0.8*-7 is -24.

Answer 2

-24.

Step-by-step explanation:

0.8*-23+0.8*-7

Use order of operation. Here we have 2 multiplications and one addition The multiplications are done first:

0.8*-23 + 0.8*-7

= -18.4 + -5.6

= -18.4 - 5.6

= -24.
