Complete the equation to represent each relationship. then solve the equation. drag and drop each term or number into the correct box to complete the equation and solve for x.

twenty-eight less than 7 times a number is the same as 20 more than the number.
( "[ ]" means empty space)
(here are the numbers: 7, 8, x, 7x, 28, 20, -8)

the equation is [ ] - [ ] = [ ] + [ ].
the solution is: x = [ ]

28 less means subtract 28

7 times a number means7x

is means equals

20 more than a number means x +20

the equation is 7x-28 =x+20

to solve combine like terms

7x-x=20+28

6x=48 divide by 6 on both sides to isolate x

x=8

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

one set of data has more variation than the other. hope this !
