Solve for n

1/2(2n+4)=5

n = 3

Step-by-step explanation:

Step  1  :

           1

Simplify   —

           2

Equation at the end of step  1  :

  1                

 (— • (2n + 4)) -  5  = 0

  2                

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  2n + 4  =   2 • (n + 2)

Equation at the end of step  3  :

 (n + 2) -  5  = 0

Step  4  :

Equation at the end of step  4  :

 n - 3  = 0

Step  5  :

Solving a Single Variable Equation :

5.1      Solve  :    n-3 = 0

Add  3  to both sides of the equation :

                     n = 3

One solution was found :

                  n = 3

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
