Let us say that:
x = age of brad
x + 2 = age of Alexandra
(x + 2) – 3 = age of Cecilia = x – 1
We are also given that:
x + x + 2 + x – 1 = 37
<span>
solving for x:</span>
3x + 1 = 37
3x = 36
x = 12 = age of brad
x + 2 = 14 = age of Alexandra
<span>x – 1 = 11 = age of cecilia</span>

Step-by-step explanation:
Answer:
x=144
Step-by-step explanation:
x/3-x/4=12
the common denominator must be 12,
4x/12-3x/12=12
since 4x-3x=x,
you have x/12=12,
x=12*12
x=144
I will use ccw for countercloclwise and cw for clockwise for this explination.
A 270 ccw rotation is the EXACT same as a 90 cw rotation. So to perform a 90 degree cw rotation all that has to be done is swap the x anf y coordinates and change the sign on the y. As a general form:
(x, y) becomes (y, -x)
In your problem R is at (3, 6) so swap the 3 and 6 to get (6, 3) now change the sign on the 3 to get R' as (6, -3)
