Question

В)(а+b)-674,есле а =830,b=243,a=1712, b=805

Answer 1

1) (830+243) - 674 = 399

2) (1712+805) - 674 = 1843

Answer 2

1 (830+243)-674=399
2 (1712+805)-674=1843

Answer 3

Let's substitute the given values of a and b into the expression (a+b)-674 and evaluate it step by step.

For the first set of values where a = 830 and b = 243:

Expression: (a + b) - 674 Substitute values: (830 + 243) - 674 Calculate: (1073) - 674 Result: 399

Now, for the second set of values where a = 1712 and b = 805:

Expression: (a + b) - 674 Substitute values: (1712 + 805) - 674 Calculate: (2517) - 674 Result: 1843

So, when a = 830 and b = 243, the expression evaluates to 399. And when a = 1712 and b = 805, the expression evaluates to 1843.
