How do you solve multi step equations with variables

2 answers:

6 0

To solve a equation you must first get the variables on the same side of the equal sign. Example: Add -2.5y to both sides so that the variable remains one side only. Now isolate the variable by subtracting 10.5 from both sides. multiply both sides by 10 so that 0.5y becomes 5y, then divide by 5.

Fill in the blank with the recursive function. Be sure to include the starting point.

erik [133]

Answer:

The recursive function that represents the number of books Ashley has at any time is

$a_n=a_{n-1}-n$

starting at

$a_1=100$

Step-by-step explanation:

Ashley has 100 books that she wants to give away at the rate of n books per week.

So,

$a_1=100\\ \\a_2=100-n=a_1-n\\ \\a_3=a_2-n\\ \\...\\ \\a_n=a_{n-1}-n$

Thus, the recursive function that represents the number of books Ashley has at any time is

$a_n=a_{n-1}-n$

starting at

$a_1=100$

Mike's plant grew 3 inches last week. Lauren's plant grew 2 1/2 times this amount. how many inches did Lauren's plant grow last

soldier1979 [14.2K]

Mike's plant plant height grew by 3 in
Lauren's grew 2 1/2 times of 3 in

So, 2 1/2 times of 3 in
= 2 1/2 x 3
= 5/2 x 3
= 15/2 = 7 1/2 inches
