Answer:

-28

Step-by-step explanation:

1) distribute "-2/5" to each term inside the parentheses:

-2/5(n+3)=10

-2/5n+-6/5=10

add "6/5" on both sides

-2/5n-6/5+6/5=10+6/5

-2/5n=50/5+6/5

-2/5n=56/5

divide both sides by "-2/5"

n=-28

hope this helps

Answer:

56.52 inches

Step-by-step explanation:

The circumference of a circle can be found using:

$c=\pi d$

We know the diameter is 18, and $\pi$ is being rounded to 3.14, so we can substitute them in.

c=3.14*18 <em>Multiply</em>

c=56.52

So, the circumference is 56.52 inches

serious [3.7K]

Answer: 13/20 of the video games at both of their houses.

Step-by-step explanation: The equation is 1/4 + 2/5. You need to find their common denominator which is 20, so the equation is now 5/20 + 8/20 = 13/20, which can't be simplified.
