Answer:
<h2>x = 9 1/3</h2>
Step-by-step explanation:
To do this, we need to do a few things. I'll put the steps separate so you can easily understand.
<h3>Step 1: Set up a proportion</h3>
<h3>Step 2: Cross multiply</h3>
6x = 14 x 4
6x = 56
6x = 9 1/3
<h3>Step 3: Check</h3>
Cross multiply to check if they equal
6 x 9 1/3 = 14 x 4
56 = 56 ✔
<h3>Step 4: Answer</h3>
x = 9 1/3

Answer:
The annual increase in the percentage of a pollution can be determined by some mathematical calculation.
Step-by-step explanation:
- In order to determine the annual percentage increase over one year for a city population, we must do the following,
- First we must subtract starting value that is the initial population of the city at the starting of the year from the final value that is the final population of the city at the end of the year.
- Now divide the whole by the starting value.
- This gives you the value of increase in the rate of growth, Now inorder to obtain it in percentage format, we must multiply the resultant value by 100.
This finally gives you the rate of increase in the population in percentage.
Let's plug in some numberz!!
And turn words into numberz.
Let x represent laps.
Let y represent total of laps.
Boys ran sixteen laps!!
Girls ran four more laps than boys.
Boys ran 16, so what's 16+4?
Correct, it's 20!!
Our equation is 0.25x = y.
Plug it in!!
What's 0.25 x 20?
Nailed it. It's 5!!
Hope this helped!
Answer:
Step-by-step explanation:
(x-3)/2 = 9
x - 3 = 18
x = 21
(y-5)/2= 6
y - 5 = 12
y = 17
(21, 17)
