Final answer:
The value of the expression (1.25 - 0.4) / 7 + 4 * 3 is 12.1214.
Step-by-step explanation:
The given expression is (1.25 - 0.4) / 7 + 4 * 3.
Let's solve it step by step:
- First, subtract 0.4 from 1.25: 1.25 - 0.4 = 0.85.
- Next, divide 0.85 by 7: 0.85 / 7 = 0.1214.
- Then, multiply 4 by 3: 4 * 3 = 12.
- Finally, add 0.1214 and 12: 0.1214 + 12 = 12.1214.
So, the value of the expression (1.25 - 0.4) / 7 + 4 * 3 is 12.1214.
