Answer:The equation to determine how much Elise will pay for a student ticket is 2x = 33
Step-by-step explanation:
Let x represent the price of one student ticket.
Elise and her dad are planning to attend the state fair and the price of an adult ticket is $21.00
The price of an adult ticket is $10.00 more than two thirds the price of a student ticket. This means that
21 = 2/3 × x + 10
The equation to determine how much Elise will pay for a student ticket would be
2x/3 + 10 = 21
2x/3 = 21 - 10 = 11
2x = 11×3 = 33
x = 33/2 = $16.5
Evaluate this function when f(x) x=3
<span>f(x)= 4x+6
</span><span>Important! The "x" is just a place-holder! And "f" is just a name.</span>
Just replace the variable "x" with "3":<span>
FOR x = 3
</span>f(3) = 4*3+6
f(3) = 12+6
f(3) = 18
The answer is 18 NOT 10 (as you said).
Using the "gradient, two-point form", we have:

From the given data, we have that

Therefore, substitute in the given values:
We have that:

Simplify further

Multiply both sides by the LCM, 5x:

Simplify:


Note that the equation of a straight line is given by Ax + By = C where A and B are coefficients of x and y respectively. C is the constant. Hence:
6x+5y=15
Answer:
10%
Step-by-step explanation:
To find the percentage, ask yourself, how much is 2000 of the original value which is 20350. This can be solved by the following equation.
2000/20350=
The answer is approximately 0.09828. Then, convert this to a percent. 9.828%. Then, round it to the nearest percent. The answer is 10%
