To solve the equation \(4 \times 3 + 5 \times r = 48\), follow these steps: 1. Calculate \(4 \times 3\): \[ 4 \times 3 = 12 \] 2. Substitute this value back into the equation: \[ 12 + 5r = 48 \] 3. Next, isolate the term with \(r\) by subtracting 12 from both sides: \[ 5r = 48 - 12 \] \[ 5r = 36 \] 4. Finally, divide both sides by 5 to solve for \(r\): \[ r = \frac{36}{5} \] \[ r = 7.2 \] Thus, the value of \(r\) is \(7.2\).
