Question

(2) (432+b) — 265; (3) (a +457) + (143 +872); (4) 96 (m + 48); (5) 516 (216- x); (6) (5432+8951) + (4568 + a + 1049).

Answer 1

Ответ:

2.432 + b) - 265 = 432 - 265 + b = 167 + b

3.(а + 457) + (143 + 872) = а + 457 + 143 + 872 = а + 1015 + 872 = а + 1887

4.96 (m + 48) = 96m + 96 * 48 = 96m + 4608

5.516 (216 - x) = 516 * 216 - 516x = 111456 - 516x

6.(5432 + 8951) + (4568 + a + 1049) = 14383 + 4568 + a + 1049 = 18982 + a

Answer 2

To solve the given expression, let's break it down step by step:

(2) + (432 + b) - 265 To solve this expression, we need to add the numbers inside the parentheses first. Adding 432 and b gives us 432 + b. Then, we subtract 265 from the sum. So the expression simplifies to 2 + 432 + b - 265.

(3) + (a + 457) + (143 + 872) Similar to the previous expression, we need to add the numbers inside the parentheses first. Adding a and 457 gives us a + 457. Adding 143 and 872 gives us 143 + 872. So the expression simplifies to 3 + a + 457 + 143 + 872.

(4) + 96 + (m + 48) Again, we add the numbers inside the parentheses first. Adding m and 48 gives us m + 48. So the expression simplifies to 4 + 96 + m + 48.

(5) + 516 + (216 - x) In this expression, we have a subtraction inside the parentheses. Subtracting x from 216 gives us 216 - x. So the expression simplifies to 5 + 516 + 216 - x.

(6) + (5432 + 8951) + (4568 + a + 1049) Adding the numbers inside the parentheses, we get 5432 + 8951 and 4568 + a + 1049. So the expression simplifies to 6 + 5432 + 8951 + 4568 + a + 1049.

Now, let's combine all the simplified expressions:

(2 + 432 + b - 265) + (3 + a + 457 + 143 + 872) + (4 + 96 + m + 48) + (5 + 516 + 216 - x) + (6 + 5432 + 8951 + 4568 + a + 1049)

To further simplify the expression, we can combine like terms. Adding all the numbers together, we get:

2 + 432 + b - 265 + 3 + a + 457 + 143 + 872 + 4 + 96 + m + 48 + 5 + 516 + 216 - x + 6 + 5432 + 8951 + 4568 + a + 1049

Simplifying this expression gives us the final result.
