In a certain county, the number of charter schools is 8 less than twice the number of alternative schools. we know that there are 36 charter schools in the county. how many alternative schools are in the county? 44 22 14 30

There are 22 alternative schools  in the country.

Step-by-step explanation:

Hi, to solve this problem we have to write an equation using the information given.

So:

Charter schools : 36

Also charter schools : 2x -8

x = alternative schools

Now, we solve the equation.

36= 2x -8

36+8 =2x

44= 2x

44/2 = x

x = 22

In conclusion, there are 22 alternative schools  in the country.

Feel free to ask for more if it´s necessary or if you did not understand something.

expression #3 is not equivalent. the others are.

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
