Answer:
Approximately 104 joggers are female
Step-by-step explanation:
The U.S census bureau reported that 9 out of every 20 joggers at female.
Let x be the number of females out of 230 joggers.
Rewrite it as
Now we can write a proportion:
Cross multiply:
![20x=9\cdot 230\\ \\2x=9\cdot 23\ [\text{Divided by 10}]\\ \\x=\dfrac{9\cdot 23}{2}=\dfrac{207}{2}=103.5\approx 104](https://tex.z-dn.net/?f=20x%3D9%5Ccdot%20230%5C%5C%20%5C%5C2x%3D9%5Ccdot%2023%5C%20%5B%5Ctext%7BDivided%20by%2010%7D%5D%5C%5C%20%5C%5Cx%3D%5Cdfrac%7B9%5Ccdot%2023%7D%7B2%7D%3D%5Cdfrac%7B207%7D%7B2%7D%3D103.5%5Capprox%20104)

Answer:
<h2>−9a³ − a² + 12a</h2>
Step-by-step explanation:
3a(a²-3a+4)-4(3a³-2a²) = 3a³ − 9a² + 12a − 12a³ + 8a²
= (3a³ − 12a³) + (− 9a² + 8a²) + 12a
= −9a³ − a² + 12a
Answer:
There are infinite ordered pairs are on the line because it has infinite solutions.
Step-by-step explanation:
5x - 2y = 6
-5x -5x
-2y = -5x + 6
-2y/2 = -5x/-2 + 6/-2
y = 5/2x - 3
5x - 2(5/2x - 3) = 6
5x - 5x + 6 = 6
6 = 6
