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
225/5 = 45 people.
Answer:
1. Let's solve for x.
−3x+5y=−6
Step 1: Add -5y to both sides.
−3x + 5y + −5y = −6 + −5y
−3x = −5y − 6
Step 2: Divide both sides by -3.
−3x
−3
=
−5y−6

2. Let's solve for x.
6x−10y=12
Step 1: Add 10y to both sides.
6x−10y+10y=12+10y
6x=10y+12
Step 2: Divide both sides by 6.
6x

=
10y+12
