2n+7+7n=13+11n

7+9n=13+11n

9n-11n=13-7

-2=6

-2/-2 6/-2

-3

first combine like terms so 2n + 7n which is 9n

so 9n + 7 = 13 + 3n + 8n

then combine on other side so 9n + 7 = 13 + 11n

then subtract 7 to 13 so 6

sp 9n + 6 = 11n

then subtract 9 to the other side so 2n

6 = 2n then divide all by 2

n= 3

Whats the fraction 18/24 reduced to its lowest items?

asambeis [7]

Hello!

$\sf Answer:$

The fraction 18/24, reduced to its lowest terms, is: $\boxed{3/4}$
_____________________________

Divide both the numerator and the denominator by the GCD of 18 and 24, which is 6:

18 ÷ 6 = 3

24 ÷ 6 = 4

It's simplest form would be 3/4. This cannot be reduced further.

Please explain what mark up is to me. Keep it simple

iogann1982 [59]

Hey there!

Markup is the percentage that the cost of an item is increased.

For example, if a company bought a pair of headphones that costed $100 and they sold it for $150, the markup was 50%, since half of the original cost was added. if the markup were 100% it would have been sold for $200, since it added 100% of the original.

I hope this helps!
