Answer:
advance tickets $30.00
same day tickets $35.00
Step-by-step explanation:
1. In this equation, you are trying to find two values so you must use system of equations. Your two equations would be:
40x +20y = 1900
x + y = 65
x represents the price of advance tickets and y represents the price of same day tickets.
2. Solve the equation by performing elimination using multiplication. Multiple one equation by a constant to get two equations that contain opposite terms.
40x + 20y = 1900
-40(x + y = 65) → -40x + -40y = -2600
3. Add the equations, eliminating one variable. (add -40x + -40y = -2600 to 40x + 20y = 1900)
40x + 20y = 1900
+ -40x + -40y = -2600
Results in: -20y = -700
Solve for y by dviding both sides by -20.
y = 35
4. Substitute the solved value into one of the equations and solve for the remaining variable.
x + 35 = 65
Subtract 35 from both sides to solve for x.
x = 30
The advance tickets were $30.00 and the same day tickets were $35.00.
Answer:
5x + 8y = 775 and x + y =125
Step-by-step explanation:
The kind of transformation the quadrilateral underwent is 180° rotation about the origin and the new vertex of Q is (4,5).
<h3>What is transformation of plane shapes?</h3>
Transformation is the change in the coordinates of the vertices that make up a plane shape.
This can be done either by translation, reflection or rotation.
Analysis:
since the x and y coordinates of P is the opposite of the coordinates of p' then there is a 180° rotation about the origin.
If vertex Q is (-4, -5), then Q' is the opposite which is (4, 5 )
In conclusion, the transformation is a 180° rotation and the coordinates of Q' are (4, 5).
