Question

Simply the Expression: 5a + 3b - 3a + 4b + 7c

Answer 1

To simplify the expression \( 5a + 3b - 3a + 4b + 7c \), we can combine like terms.

1. Combine the \( a \) terms:
\[
5a - 3a = 2a
\]

2. Combine the \( b \) terms:
\[
3b + 4b = 7b
\]

3. The \( c \) term remains as is:
\[
7c
\]

Putting it all together, the simplified expression is:
\[
2a + 7b + 7c
\]

Answer 2

wrong

Answer 3

Let's go through the simplification step-by-step again.

Starting with the expression:

\[
5a + 3b - 3a + 4b + 7c
\]

1. **Combine the \( a \) terms**:
\[
5a - 3a = 2a
\]

2. **Combine the \( b \) terms**:
\[
3b + 4b = 7b
\]

3. The \( c \) term remains unchanged:
\[
7c
\]

Now, putting it all together gives us:

\[
2a + 7b + 7c
\]

It appears the previous response was indeed correct. The simplified expression is \( 2a + 7b + 7c \). If there is a specific aspect of the problem or expression that you would like to clarify or if there was a misunderstanding, please let me know!

Answer 4

Simplify the Expression: 4.5x - 2 + 3.7x + 6.5

Answer 5

To simplify the expression \( 4.5x - 2 + 3.7x + 6.5 \), we will combine like terms.

1. **Combine the \( x \) terms**:
\[
4.5x + 3.7x = (4.5 + 3.7)x = 8.2x
\]

2. **Combine the constant terms**:
\[
-2 + 6.5 = 4.5
\]

Now, putting it all together gives us:

\[
8.2x + 4.5
\]

So, the simplified expression is:

\[
\boxed{8.2x + 4.5}
\]
