Would be really nice if I could get some help on how to do this, not only the answers. Equations and Expressions 1

Calculate if the value given for the variable is the solution or not.

6x-13=5 x=3

⅓(x+4)=20 x=48

4x+5.25=13.25 x=2

Solve

x/7=11

x-5=4

4x=20

x+3=5

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.)
