Which equation could be used to solve the problem? Oscar averaged 4 yards per carry in the football game. If he carried the ball 16 times, how many yards did he gain (y) ? A. y = 4 • 16 B. y = 4 + 16 C. y = 4 : 16 D. y = 16 : 4

He needs a down payment of $3000. If he saves $340 each month, about how many months will it take him to save the down payment?

Find both unit rates. 374 students for every 20 teachers A. About 0.053 students/teachers and 18.7 teachers/students B. 374 students/teachers and 18.7 teachers/students C. 18.7 students/teachers and about 0.053 teachers/students D.

Identify the equations that have one solution, infinitely many solutions, or no solution. A. 1/2y + 3.2y = 20 B. 15/2 + 2z = 1/4 = 4z + 29/4 - 2z C. 3z + 2.5 = 3.2 + 3z D. 1.1 + 3/4x + 2 = 3.1 = 3/4x E. 4.5r = 3.2 + 4.5r F. 2x + 4 = 3x + 1/2
