QuestionWrite an expression for the sequence of operations described below. subtract cc from 7 , then subtract 8 from the result Do not simplify any part of the expression.

Studdy Solution

STEP 1

What is this asking? We're taking the number 7, subtracting cc from it, and then subtracting 8 from *that* result.
We need to write this out as a single math expression without simplifying. Watch out! The order of subtraction matters!
Subtracting cc from 7 is different from subtracting 7 from cc.

STEP 2

1. Set up the initial subtraction
2. Subtract 8 from the result

STEP 3

We **start with 7** and we're told to subtract cc from it.
So we write that as 7c7 - c.
This represents the result of the first operation.

STEP 4

Now, we need to subtract 8 from the result of the previous step.
That result was 7c7 - c.
So we take that whole thing and subtract 8: (7c)8(7 - c) - 8.
We're told *not* to simplify, so we leave it just like that!

STEP 5

The expression representing the sequence of operations is (7c)8(7 - c) - 8.
