Question

1. -4.8f + 6.4 = -8.48

Explanation:

Step1: Subtract 6.4 from both sides

To isolate the term with \( f \), we subtract 6.4 from both sides of the equation \(-4.8f + 6.4=-8.48\). This gives us \(-4.8f+6.4 - 6.4=-8.48 - 6.4\). Simplifying both sides, we get \(-4.8f=-14.88\).

Step2: Divide both sides by -4.8

Now, to solve for \( f \), we divide both sides of the equation \(-4.8f = - 14.88\) by \(-4.8\). So, \(f=\frac{-14.88}{-4.8}\). Calculating the right - hand side, we know that dividing two negative numbers gives a positive result. And \(\frac{14.88}{4.8}=3.1\).

Answer:

\(f = 3.1\)
