Question: User: 1.8y + 0.72
1. **State the problem:** Simplify or understand the expression $$1.8y + 0.72$$.
2. **Identify terms:** The expression consists of two terms: $$1.8y$$ (a term with variable $$y$$) and $$0.72$$ (a constant).
3. **Check for like terms:** Since one term contains $$y$$ and the other is a constant, they cannot be combined further.
4. **Factor if needed:** We can factor out the common factor $$0.72$$:
$$1.8y + 0.72 = 0.72 \times \frac{1.8y}{0.72} + 0.72 = 0.72(\cancel{\frac{1.8}{0.72}}y + 1)$$
Calculate $$\frac{1.8}{0.72}$$:
$$\frac{1.8}{0.72} = 2.5$$
So,
$$1.8y + 0.72 = 0.72(2.5y + 1)$$
5. **Final expression:** The factored form is $$0.72(2.5y + 1)$$.
This is the simplest form unless you want to leave it as the original expression.
