Combine like terms to create an equivalent expression. 3.4-2.8 d+2.8 d-1.3

Identify Like Terms: Identify like terms in the expression 3.4 - 2.8d + 2.8d - 1.3. Like terms are terms that have the same variable raised to the same power. In this expression, -2.8d and +2.8d are like terms. The numbers 3.4 and -1.3 are also like terms because they are both constants.Combine Like Terms -2.8d and +2.8d: Combine the like terms -2.8d and +2.8d. -2.8d + 2.8d equals 0 because adding a number and its negative cancels each other out.Combine Like Terms 3.4 and -1.3: Combine the like terms 3.4 and -1.3. 3.4 - 1.3 equals 2.1 because subtracting 1.3 from 3.4 gives us the difference.Write Simplified Expression: Write the simplified expression. Since -2.8d and +2.8d cancel each other out, we are left with the constant terms. The simplified expression is 2.1.

3.4-2.8 d+2.8 d-1.3

Identify Like Terms: Identify like terms in the expression $3.4 - 2.8d + 2.8d - 1.3$ . Like terms are terms that have the same variable raised to the same power. In this expression, $-2.8d$ and $+2.8d$ are like terms. The numbers $3.4$ and $-1.3$ are also like terms because they are both constants.
Combine Like Terms $-2.8d$ and $+2.8d$ : Combine the like terms $-2.8d$ and $+2.8d$ . $-2.8d + 2.8d$ equals $0$ because adding a number and its negative cancels each other out.
Combine Like Terms $3.4$ and $-1.3$ : Combine the like terms $3.4$ and $-1.3$ . $3.4 - 1.3$ equals $2.1$ because subtracting $1.3$ from $3.4$ gives us the difference.
Write Simplified Expression: Write the simplified expression. $\newline$ Since $-2.8d$ and $+2.8d$ cancel each other out, we are left with the constant terms. The simplified expression is $2.1$ .
