<h2>Explanation:</h2>
Rigid motions are transformations we perform on a figure in order to move it without changing the size or shape of it. They are also called <em>congruence transformations </em>because we can map one figure onto other figure so they will maintain every condition in order to be congruent.
Rigid motions are the following:
- Reflections: Here we reflect the figure across a line
- Translations: Here we move the figure either horizontally or vertically
- Rotations: Here we turn the figure either counterclockwise or clockwise.
So sequence of rigid motions could be any combination we get from the mentioned transformations. For instance:
Perform the transformation of triangle ΔABC following this sequence:
1. Translate the figure 2 units right and 4 units down
2. Reflect the figure across the x-axis
3. Rotate the figure 90 degrees in clockwise direction

The average is found by adding all the temperatures together, then dividing by the number of days.
Since the average for five days was 63, then the total of the temperatures need to equal 63 x 5 = 315.
The total for the first four days was : 56 + 60 + 79 + 70 = 265
The fifth day is 315 - 265 = 50 degrees.
Answer:
Step-by-step explanation:
84 = 2 * 2 *3 * 7
4 x 7 is 28, and 8 x 7 is 56. You can use 4 x 7 to find 8 x 7 by multiplying that first and doubling that quotient.
Half of 56 is 28, therefore doubling that allows us to find the quotient of 8 x 7.
Answer:
x=9
Step-by-step explanation:
80+6x+16=17x-3
=>17x-3-6x-16=80
=>11x-19=80
=>11x=80+19
=>11x=99
=>x=99/11
therefore
x=9
