Answer: 81280
Step-by-step explanation:
From the question, we are informed that there are 635,000 residents in Jones County and 12.8% are under the age of 5.
The number of residents that are under the age of 5 will be calculated as:
= 12.8% × 635000
= 0.128 × 635000
= 81280
Hey there!
The first step in solving this equation is
- using the Distributive property & distributing 2:
2(7x-3)=9
14x-6=9
Now, add 6 to both sides:
14x=15
Divide both sides by 14:
x=15/14
Hope everything is clear.
