Write the difference 30 – (–12) as a sum, then simplify.
Evaluate the following expression. Show all steps.
18 + 6m for m = 2
I will be happy to critique your work on this.
Well..these are the only two questions I'm stuck on.
for 18 + 6m for m = 2 , do 6 x m or 2 first then add 18 to your answer
To write the difference 30 - (-12) as a sum, we can change the subtraction into addition by changing the sign of -12 to its opposite. The opposite of -12 is 12. So, we have:
30 + 12
Now, to simplify this sum, we can add the numbers together:
30 + 12 = 42
Therefore, the difference 30 - (-12) is equal to 42.
Now, let's evaluate the expression 18 + 6m, where m = 2.
To find the value of the expression, we substitute m with 2 and simplify:
18 + 6(2)
Next, we perform the multiplication:
18 + 12
Finally, we add the numbers together:
18 + 12 = 30
Therefore, the value of the expression 18 + 6m, where m = 2, is equal to 30.
