Choose only 3 correct ones
The three correct expressions for 8p + 8 are:
- 8 (p + 1)
- 2 (5p - 4)
- 4 (2p + 2)
In the given expression 3/8x - 4.5, the constant is represented by -4.5.
To understand this, let's break down the expression:
1. 3/8x: This is a term that involves both a coefficient (3/8) and a variable (x). When x has a specific value plugged in, it becomes a numerical value.
2. -4.5: This is a term that does not involve any variables. It is a numerical value that remains constant. It does not change regardless of what value x takes.
So, in the given problem, when x = 0.4, the expression can be rewritten as:
3/8(0.4) - 4.5
To evaluate this, we need to simplify:
3/8(0.4) = 3/8 * 0.4 = 0.12
Now, substitute the value back into the expression:
0.12 - 4.5
Here, the -4.5 is the constant term since it does not involve any variables.
