Answer:

x=3

Step-by-step explanation:

If f(x)=11, then 11=3x+2.

Subtract 2 on both sides of the equation.

11-2=3x+2-2

9=3x

Divide on both sides by 3

9/3 = 3x/3

3=x

Elise and her dad are planning to attend the state fair. An adult ticket is $21.00. The price of an adult ticket is $10.00 more

belka [17]

Answer:

C)two thirds x + 10 = 21

Step-by-step explanation:

The equation for determining how much it would be paid for the student tickets is shown below:

Given that

The ticket of an adult is $21

Now let us assume the price of the student ticket be x

So two third would be 2 ÷ 3x

And for adult it would be

2 ÷ 3x + 10

Now the equation is

2 ÷ 3x + 10 = 21

So after solving this the option c is correct

And the rest of the options are wrong
