Answer:
Step-by-step explanation:
Let the age of a man = x
Age of his brother = y
Three yrs hence, a man will be three time his brother age
This is written as:
x + 3 = 3(y + 3)
x + 3 = 3y + 9 .... Equation 1
The sum of present age is 18
= x + y = 18
x = 18 - y
We substitute 18 - y for x in Equation 1
find their present age
18 - y + 3 = 3y + 9
Collect like terms
21 - 9 = 3y + y
12 = 4y
y = 12/4
y = 3 years
x = 18 - y
x = 18 - 3
x = 15 years

<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

Answer:
B) 4%
Step-by-step explanation:
Interest = Principal x Rate x Time
108 = 900 x 3 x r
108 = 2700r
108/2700 = r
r = 0.04 or 4%
