The solution of the equation (√x-8) + 2 = 7 is x = 13.
According to the given question.
We have an equation
Since, we solve the above equation for x .
Therefore,
⇒ (√x - 8) = 7 - 2
⇒ (√x - 8) = 5
Squarring both the sides.
⇒ x - 8 = 5
⇒ x = 5 + 8
⇒ x = 13
Hence, the solution of the equation (√x-8) + 2 = 7 is x = 13.

Answer:
The expression for the cost of soda is 100 × cents
Step-by-step explanation:
Given as :
The quantity of hot dogs sold by vendor = h
The quantity of sodas sold by vendor = s
The total cost of hot dogs and soda = $ d
Let The price of hot dogs = $ x
And The price of soda = $ y
Now, According to question
The price of hot dogs is twice as much as soda
so, $ x = 2 × $ y
I.e x = 2 y
and $ x h + $ y s = $ d
Or , 2 × $ y h + $ y s = $ d
Or, y =
∵ 1 dollar = 100 cents
So, the price of = 100 ×
cents
Hence The expression for the cost of soda is 100 × cents Answer
