Answer:

n = -10

Step-by-step explanation:

5n = 8n + 30

you move 8n over by subtracting it from both sides

5n -8n = 8n -8n +30

add like terms

-3n = 30

then divid both sides by -3

-3n/-3 = 30/-3

n = -10

To find n
1. Subtract 8n from both side to get -3n=30
2. Divide both sides by -3 to get n=-10

We have the following general rule for exponents:

$a^n\cdot a^m=a^{n+m}$

then, in this case we have the following:

$3^3\cdot3^{-2}=3^{3+(-2)}=3^{3-2}=3^1=3$

therefore, the answer is 3

Answer:

3/8

Step-by-step explanation:

1- 1/4 +(1/2 x 3/4)

1. subtract 1/4 to get 3/4 (how much time she has left in class).

2. multiply 3/4 by 1/2 to find how much half of 3/4 is.

3. Half of 3/4 is 3/8 so that's how much time she spent on the balance beam.
