Find the unknown number in each equation: \r\n51-g=20

Identify total tape needed: Step 1: Identify the total amount of tape needed and the amount per roll. We know the electrician needs 8,000 cm of tape, and each roll contains 2,000 cm. Calculation: 8,000 cm total / 2,000 cm per roll.Calculate rolls needed: Step 2: Calculate the number of rolls needed by dividing the total tape required by the amount per roll. Calculation: 8,000 ÷ 2,000 = 4.

51-g=20

Identify total tape needed: Step $1$ : Identify the total amount of tape needed and the amount per roll. $\newline$ We know the electrician needs $8,000 \, \text{cm}$ of tape, and each roll contains $2,000 \, \text{cm}$ . $\newline$ Calculation: $\frac{8,000 \, \text{cm} \, \text{total}}{2,000 \, \text{cm} \, \text{per roll}}$ .
Calculate rolls needed: Step $2$ : Calculate the number of rolls needed by dividing the total tape required by the amount per roll. $\newline$ Calculation: $8,000 \div 2,000 = 4$ .
