None of the options give the same fees for a session of x hours.
Given,
x + 20/2 = 3x
when two tutoring services with different rate plans charge the same fees for a session of x hours.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
x + 20/2 = 3x
x + 10 = 3x
A) x= 10
10 + 10 = 3*10
20 ≠ 30
B) x=4
4 + 10 = 3 * 4
14 ≠ 12
C) x= -14
-14 + 10 = 3 * -14
-4 ≠ 42
D) x=-17
- 17 + 10 = 3 * - 17
-7 ≠ -51
Here, none of the options give the same fees for a session of x hours.
Thus, none of the options give the same fees for a session of x hours.

Answer:
Option b is the correct answer
Step-by-step explanation:
The graph in the picture is the graph of a quadratic equation and it takes the shape of a parabola.
The points on the x axis through which the parabola cuts across is used to determine the solution of the quadratic equation.
Looking at the parabola formed from the plotted points, it cuts the x axis at
x = -1 and x= -2
These are the factors of the equation. To get the equation, we multiply the factors.
x= -1, x +1 = 0
x =-2 , x + 2= 0
The equation is (x+1)(x+2)
Expanding the brackets,
x×x + x×2 +1×x + 1×2
= x^2 + 2x + x +2
= x^2 + 3x +2 = 0
Option b is the correct answer

Answer:
x=333.33%
Step-by-step explanation:
hello
you can resolve this by using the rule of 3,let´s see
75 oranges =100%
250 oranges = x%?
75 oranges* x%=250 oranges *100%
x=333.33%
Have a great day.
