Write an absolute value inequality for the recommended air pressure range for each type of ball. Use the variable x for the ball

kirill115 [55]

Answer:

For Soccer ball:

x = | 12. 05 + 3.55 |

For basketball:

x = | 8.00 + 0.5 |

For volleyball:

x = | 4.44 + 0.18 |

Step-by-step explanation:

Given the following :

Let x = ball's actual air pressure

_________avg Recommended psi ___tolerance

Soccer ball____ 12. 05 ____________+3.55

Basketball _____8. 00_____________+0.5

Volleyball _____ 4.44 _____________ + 0.18

Actual air pressure = | average recommended psi + tolerance |

Hence ;

For Soccer ball:

x = | 12. 05 + 3.55 |

For basketball:

x = | 8.00 + 0.5 |

For volleyball:
