Answer:
30 is the cost of clothes Kyle bought.
Step-by-step explanation:
Given: Kyle spend 1/5 of his money on clothing.
Remaining money is 120.
Lets assume the total money Kyle had be "x".
∴ Money spent on clothes = 
Now, putting up value in the equation to find the total amount of money.
We know, money remaining is 120
Taking LCD subtract the fraction.
⇒ 
⇒ 
⇒
Multiplying 5 both side
⇒
dividing 4 on both side.
∴
∴ x= 150
Kyle has total 150 money to spend.
Kyle spent 
of his total money on clothing.
⇒ cost of clothes kyle bought= 
Hence, Kyle spent 30, which was the cost of clothes kyle bought.

Answer:
the coordinates of the vertex are: (2.5, -24.5)
Step-by-step explanation:
Recall that when we have a quadratic in its standard form:
the position of the x-coordinate for the vertex can be obtained via:
Then in order to find the vertex, first we write the expression in standard form:
Now that we have the values for the parameters "
" and "b" we find the x of the vertex:
Now we use this x-value in the function to find the correspondent y-value of the vertex:
Then, the coordinates of the vertex are: (2.5, -24.5)
