What is the formula for the combined ages of two people in the future?

Back

If one person is x years old and the other is y years younger, their combined ages in t years can be expressed as (x + t) + ((x - y) + t) = 2x - y + 2t.

How do you factor an expression in simplest form?

Back

To factor an expression in simplest form, identify the greatest common factor (GCF) of the terms and express the original expression as a product of the GCF and the remaining terms.

Front

What is the significance of the coefficients in an algebraic expression?

Back

Coefficients are the numerical factors that multiply the variables in an algebraic expression, determining the weight or influence of each variable in the expression.

How do you simplify the expression \( \frac{3}{2}b - 6.5b \)?

Back

To simplify \( \frac{3}{2}b - 6.5b \), convert 6.5 to a fraction (\( \frac{13}{2}b \)), then combine: \( \frac{3}{2}b - \frac{13}{2}b = -\frac{10}{2}b = -5b \).
