  1. Day 13 Assignment: Systems Pt 2

  2. 1. What is the x-coordinate of the solution to the system of linear equations below? 4x + 5y = 8 2x − 3y = −18 • F −4 • G −3 • H 3 • J 4

  3. 2. A restaurant sold a total of 418 large and small hamburgers during one day. Total hamburger sales were $1077. Large hamburgers sold for $3, and small hamburgers sold for $1.50. Which system of linear equations can be used to find l, the number of large hamburgers sold, and s, the number of small hamburgers sold? Al+ s= 1077 C 1.50l + 3s = 418 3l + 1.50s = 418l+ s= 1077 B l+ s= 418 Dl+ s= 418 3l + 1.50s = 1077 1.50l + 3s = 1077

  4. 3. What is the y intercept of 12y = 144x – 36?

  5. 4. Which is the solution to this pair of linear equations? 5y − 2x = 6 3x − 2y = 13 • A (3, −2) • B (5, −2) • C (7, 4) • D (8, −4)

  6. 5. An investor has a total of 45 one-ounce ingots, made of either gold or silver, worth $7636.50. The value of a gold ingot is $280.00, and the value of a silver ingot is $4.25. Which system of equations can be used to find g, the number of gold ingots, and s, the number of silver ingots? A g− s= 45 C g+ s= 45 280.00g + 4.25s = 7636.50 4.25g + 280.00s = 7636.50 B g+ s= 45 D g− s= 7636.50 280.00g + 4.25s = 7636.50 280.00g + 4.25s = 45
