Solve. 14/n+7=10/n-4 N=5.25 N=3.5 N=31.5 N=30

Ilya [14]

Answer:

n=31.5

Step-by-step explanation:

The given question is:

$\frac{14}{n+7}=\frac{10}{n-4}$

Cross multiply to get:

$14(n-4)=10(n+7)$

Expand the parenthesis:

$14n-56=10n+70$

Group similar terms:

$14n-10n=70+56$

Combine the like terms

$4n=126$

Divide both sides by 4

$n=\frac{126}{4}$

n=31.5

How do you find the whole from a percent?

mr Goodwill [35]

N x 100 = n%

An example:
12 is 20% of 60. In order to get 12 percent of 60, all you need to do is to divide 12 with 60. To get the percent means to get the parts of 100. To get it in the form of percent, just multiply the quotient by 100. 12/60=.2 x 100 = 20% .
