1. Multiply both sides by 4x-1
   $\frac{1}{7} (4x-1)=3$
2.Simplify $\frac{1}{7} (4x-1) to \frac{4x1}{7} 
$
   $\frac{4x-1}{7} =3$
3.Multiply both sides by 7
   4x-1=3x7
4.Simplify 3*7 to 21
   4x-1=21
5. Add one to both sides
   4x=21+1
6. Simplify 21+1 to 22
   4x=22
7.Divide both sides by 4
    x= $\frac{22}{4}$
8.Simplify $\frac{22}{4}$ to $\frac{11}{2}$

35 of the apartments have a balcony and 55 of them don't. An apartment is randomly selected as part of a survey. What is the pro

kobusy [5.1K]

Answer:

39%

Step-by-step explanation:

It is given that 35 apartments have balconies in them.

While 55 apartments do not have balconies in them.

Total number of balconies is the sum of the apartments. i.e. 35 + 55

= 90 apartments

Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.

i.e.

$=\frac{35}{90}$

= 0.38888888

Multiplying by 100, we get

= 0.388888 x 100

= 38.8888 %

= 39 %
