Final answer:
The third step in the algorithm A = 23 - 7/5 * 4 is to subtract the result of the multiplication (5.6) from 23, resulting in a final answer of A = 17.4.
Step-by-step explanation:
The third step of the algorithm for calculating A = 23 - 7/5 * 4 involves performing the multiplication part of the expression first, due to the order of operations (PEMDAS/BODMAS). So, the first two steps would be:
- Compute 7/5 which gives you 1.4.
- Multiply that result by 4, resulting in 5.6.
The third step is to subtract the result of step two from 23:
- Subtract 5.6 from 23, which results in 17.4.
Therefore, the third step yields the final answer A = 17.4.
