Question

-2.81 = -2.9 + 0.1c

Explanation:

Step1: Add 2.9 to both sides

To isolate the term with \( c \), we add 2.9 to both sides of the equation. This gives us:
\( -2.81 + 2.9 = -2.9 + 2.9 + 0.1c \)
Simplifying the left - hand side: \( -2.81+2.9 = 0.09 \), and the right - hand side simplifies to \( 0.1c \) (since \( - 2.9+2.9 = 0 \)). So now our equation is \( 0.09=0.1c \).

Step2: Divide both sides by 0.1

To solve for \( c \), we divide both sides of the equation \( 0.09 = 0.1c \) by 0.1. Using the formula \( c=\frac{0.09}{0.1} \), we calculate that \( c = 0.9 \).

Answer:

\( c = 0.9 \)
