Answer 2

To find the value of the expression |1.3a-2|5+b| when a = -10 and b = -7, we can substitute the values of a and b into the expression and perform the calculations step by step.

Given: a = -10, b = -7 Expression: |1.3a-2|5+b|

Step 1: Replace 'a' with -10 |1.3(-10) - 2|5 + b|

Step 2: Perform the calculation inside the absolute value |(-13) - 2|5 + b|

Step 3: Calculate the absolute value (remove the negative sign if present) | -15 |5 + b|

Step 4: Calculate the absolute value |15|5 + b|

Step 5: Replace 'b' with -7 |15|5 - 7|

Step 6: Perform the calculation inside the absolute value |15|-2

Step 7: Calculate the absolute value 15 + 2

Step 8: Final Result 17

So, the value of the expression |1.3a-2|5+b|, when a = -10 and b = -7, is 17.
