Answer:
D
Step-by-step explanation:
The sum of a number and twenty-three less than that number" as a mathematical expression is x + (x – 23)
I mean its the only answer with sum and "less than" because that usually means you need to subtract, I hope this helps
If f(x) = 3x - 12 and x = 9
then substitute 9 in place of x
f(9) = 3(9) - 12
f(9) = 27 - 12
f(9) = 15

Answer: 9) 15m-30
11.) 5b-5
Step-by-step explanation:
With Distributive Property, you are basically looking at the question like this: (5*3)m +(5*-6)
When you take a negative and multiply it with a positive it will be a negative number.
it would then get simplified as
15m-30
Same with number 11. look at it as
(5*1)b +(5*-1)
again a negative and a positive gets you a negative so your answer would be
5b-5
