question 11
lesson 6-4: extra practice
solve $8f = 40$.
$f = \underline{quadquad}$

Explanation:

Step1: Isolate the variable \( f \)

To solve for \( f \) in the equation \( 8f = 40 \), we divide both sides of the equation by 8. This is based on the division property of equality, which states that if we divide both sides of an equation by the same non - zero number, the equation remains true.

$$ \frac{8f}{8}=\frac{40}{8} $$

Step2: Simplify both sides

Simplifying the left - hand side, \( \frac{8f}{8}=f \). Simplifying the right - hand side, \( \frac{40}{8} = 5 \).

Answer:

\( f = 5 \)
