Alicia cashed her paycheck and used half her earnings to take three friends out to dinner. she spent $42.15 and she brought home more than $20. write an inequality to represent the situation, using x to represent the amount of alicia's paycheck

What is the sum of these mixed numbers 2 1/8 + 4 3/8

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Asap! i'm not good math and i'm lost.
