please help me I'm confused .-.


write a compound inequality for each situation


14. Children and senior citizens receive a discount on tickets at the movie theater. To receive a discount, a person must be under 10 years old, or 65 years or older.

15. The scores on the last test ranged from 65% to 100%.

16. Mercury is one of only 2 elements that are liquid at room temperature. Mercury is nonliquid for temperatures less than -38°F or greater than 673.8°F. Write a compound inequality for the temperatures at which mercury in nonliquid.​

Answer 1

Answer:

14)A compound inequality is $10>x\geq 65$

15)A compound inequality is $65\% <x< 100\%$

16)A compound inequality for the temperatures at which mercury in nonliquid. is $-38^{\circ} F>x> 673.8^{\circ}F$

Step-by-step explanation:

14)

Let x be the age of person

We are given To receive a discount, a person must be under 10 years old, or 65 years or older.

So, $x<10$ or $x \geq 65$

So, a compound inequality is $10>x\geq 65$

15) Let x be the percentage scored

We are given that The scores on the last test ranged from 65% to 100%.

So,$65\% <x< 100\%$

So, a compound inequality is $65\% <x< 100\%$

16)

Let x be the temperature

We are given that Mercury is nonliquid for temperatures less than -38°F or greater than 673.8°F

So,$x< -38^{\circ} F$ or $x > 673.8^{\circ}F$

$-38^{\circ} F>x> 673.8^{\circ}F$

So, a compound inequality for the temperatures at which mercury in nonliquid. is $-38^{\circ} F>x> 673.8^{\circ}F$
