Answer: 60,62,64

Step-by-step explanation:

69+62+64=186

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

You need to create a chart like the one attached and put your own values in it. The teacher wants atleast 3 inputs and outputs but 4 or 5 is better. You first need to create a rule (EX: x+1=y)
