L= a+(n-1)d <br><br>SOLVE FOR N

Deffense [45]

Answer:

$n = \frac{l-a}{d}+1$

Step-by-step explanation:

$l= a+(n-1)d\\$

$l -a =(n+1)d$

Divide both sides of the equation by d

$\frac{l-a}{d} = \frac{(n-1)}{d}\\ \\\frac{l-a}{d} = n-1\\\\\frac{l-a}{d}+1 = n$

There were 30 cookies in a jar. Eileen divided the cookies into 12 equal shares. How many cookies were there in each share?

Sedbober [7]

The answer is 2.5 cookies also known as 2 and 1/2 Because 12 can go into 30, twice , which gives us 24 and 30-24= 6 so we put a decimal point to the right of 2 and we put a 0 and bring the zero down to make 60. 12 goes into 60, 5 times so the answer is 2 1/2 or 2.5
