To simplify x^2-3 =5x
You would first subtract 5x from both sides
X^3-5x-3
Next you would plug this into the quadratic equation:
X=5+/- the square root of: -5^2 -4(1)(-3)/2(1)
Then simplify,
5+/- the squareroot of 24 + 12 / 2
5+/- The squareroot of 36 /2
5+/- 6 / 2
Then solve if it’s an addition or subtract
5+6/2
X=11/2 or 5 1/2
5-6/2
X= -1/2
The answer is x=-1/2 or x=11/2
Hope this helps
I’m guessing it would be 21/24
Part A
Distribute the one-half.
1.24g + 0.87m + 0.98z
Part B
(29.68 - x) + 14.45
Or simplified to 44.13 - x
Part C
a = number of times at the store
b = gloves' price
c = hat's price
Hello!
We have the following data:
a1 (first term or first year salary) = 32000
r (ratio or annual increase) = 300
n (number of terms or each year worked)
We apply the data in the Formula of the General Term of an Arithmetic Progression, to find in sequence the salary increases until it exceeds 34700, let us see:
formula:
* second year salary
![a_2 = a_1 + (2-1)*300](https://tex.z-dn.net/?f=%20a_2%20%3D%20a_1%20%2B%20%282-1%29%2A300%20)

![\boxed{a_3 = 32600}](https://tex.z-dn.net/?f=%20%5Cboxed%7Ba_3%20%3D%2032600%7D%20)
* fourth year salary

Answer:
of ice cream
Step-by-step explanation:
Given
Number of friends = 8
Size of ice cream = 1/6 quarts
Required
Total ice cream served
Let n represent the number of friends, s represent the size of ice cream and t represents total ice cream served;
t is calculated as thus;
![t = n * s](https://tex.z-dn.net/?f=t%20%3D%20n%20%2A%20s)
![t = 8 * \frac{1}{6} quarts](https://tex.z-dn.net/?f=t%20%3D%208%20%2A%20%5Cfrac%7B1%7D%7B6%7D%20quarts)
![t = \frac{8}{6} quarts](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B8%7D%7B6%7D%20quarts)
Divide numerator and denominator by 2
![t = \frac{4}{3} quarts](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20quarts)
Hence, she serves
in total
