the Jones family received 19 pieces of mail on November 3. The mail consisted of letters, bills, magazines, and ads. How many letters did they receive if they received five more ads than bills, the same number of letters as magazines, and three more bills than magazines?​

2 letters.

Step-by-step explanation:

Consider the number of bills as x.

Since they recieve "5 more ads than bills" ads is x+5.

And since they recieved "three more bills than magazines," magazines is x-3.

And since they recieved the same number of magazines and letters, letters is also x-3.

bills=x

ads=x+5

magazines=x-3

letters=x-3.

19 pieces of mail = bills +ads + magazines + letters

plug in the information: 19 = x + (x+5) + (x-3) + (x-3)

group the x's and add the numbers: 19 = 4x -1

solve for x:  x=5

We are still not done since x is the number of bills, not letters.

Plug the value of x into "letters = bills-3."

so...

Letters = 5 - 3

Letters = 2.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
