A football team scored 9 times in a game for a total of 54 points. Each touchdown with the extra point is worth 7 points. Each field goal is worth 3 points. If t is the number of touchdowns and f is the number of field goals, which system of equations could be used to represent the scoring in the football game?

• f+t=54

  7t+3f=12

• t+f=7

  7t+3f=54

• t+f=3

  7t+3f=54

• t+f=9

  7t+3f=54

A football team scored 11 times in a game for a total of 66 points. Each touchdown with the extra point is worth 7 points. Each field goal is worth 3 points. If t is the number of touchdowns and f is the number f field goals, Find system of equations could be used to represent the scoring in the football game?

• f+t=66

  7t+3f=11

• t+f=7

  7t+3f=66

• t+f=3

  7t+3f=66

• t+f=11

  7t+3f=66

Jasmine has a jar of 298 nickels and dimes she has been collecting. The total value of the coins is $19.80. Which system of linear equations and solution can be used to represent the number of nickels and dimes Jasmine has in her collection?

• n+d=298

  5n+10d=198

• n+d=198

  5n+10d=298

• n+d=298

  10n+5d=198

• n+d=198

  10n+5d=298
