statuscvo [17]

Answer: 45

Step-by-step explanation:

In​ 2016, 1 out of every 5 people under the age of 50 used a cell phone to read​ e-books. This means that 2 out of every 10 people under the age of 50 used a cell phone to read​ e-books. Also, 3 out of every 15 people under the age of 50 used a cell phone to read​ e-books.

Therefore, if there were x people under the age of 50 in​ 2016, then the number that used a cell phone to read​ e-books would be

1/5 × x = x/5

If there were approximately 225 million people under the age of 50 in​ 2016, then the number that were likely to have read an​ e-book on a cell​ phone is

) Alon started in 60% of his team's basketball games this season. He started a total of 12 games. About how many games did Alon'
kvv77 [185]

Answer:

D

Step-by-step explanation:

Let x = total number of basketball games that was played by the team this season.

Alon started in 60% of his team’s basketball games this season. This means that he started in a total number of 60 percent of x basketball games this season.

60% of x basketball games this season = 60/100 × x

= 0.6×x = 0.6x

From the information given, Alon started a total of 12 basketball games this season. Therefore,

0.6x = 12

x = 12/0.6 = 20
