Identify Total Amount: Identify the total amount of electrical tape needed and the amount of tape on each roll. The electrician needs 8,000 centimeters of electrical tape, and each roll contains 2,000 centimeters of tape.Determine Rolls Needed: Determine the number of rolls needed by dividing the total amount of tape by the amount of tape on each roll. Calculate 8,000 cm ÷ 2,000 cm/roll. 8,000 ÷ 2,000 = 4Conclude Number of Rolls: Conclude the number of rolls the electrician should order. The electrician should order 4 rolls of tape.

Q. Solve using elimination.

\newline

\begin{array}{l} -6 x+10 y=10 \\ -3 x+2 y=20 \end{array}

Identify Total Amount: Identify the total amount of electrical tape needed and the amount of tape on each roll. $\newline$ The electrician needs $8,000$ centimeters of electrical tape, and each roll contains $2,000$ centimeters of tape.
Determine Rolls Needed: Determine the number of rolls needed by dividing the total amount of tape by the amount of tape on each roll. $\newline$ Calculate $8,000 \, \text{cm} \div 2,000 \, \text{cm/roll}$ . $\newline$ $8,000 \div 2,000 = 4$
Conclude Number of Rolls: Conclude the number of rolls the electrician should order. The electrician should order $4$ rolls of tape.
