Answer:
a = 11/12
Step-by-step explanation:
1/3 + a =5/4
Subtract 1/3 from each side
1/3-1/3 + a =5/4-1/3
a = 5/4 -1/3
Get a common denominator of 12
a = 15/12 - 4/12
a = 11/12
We can setup an equation for this.
Boys to Girls = 2:7
Boys = x
Girls = 250+x
Setup the ratio
x:(250+x) = 2:7
x / (250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100

<h2>Hello!</h2>
The answer is:
The interval notation will be: (-∞,-1.59) and (-4.41,∞+)
<h2>Why?</h2>
To solve the expression, we need to perform the following steps:
- Find the roots or zeroes of the expression:
Using the quadratic equation, we have:

We are given the quadratic expression:

Where,

Then, substituting and calculating we have:

- Inequality interpretation:
Now that we already know the roots of the quadratic expression, and we can see that the parabola open upwards (positive quadratic coefficient), we can conclude that the function is less than 0 between the numbers -4.41. and -1.59
The interval notation will be:and (-∞,-1.59) and (-4.41,∞+)
Have a nice day!
