Well to find this first you will divide the area by the length.
If you can use a calculator just put 11.875/4.75 which gives you as your width 2.5.
If you can't then change them into irregular fractions so...
11 7/8 --> 95/8
4 3/4 --> 19/4
Then divide them
95/8 / 19/4
95/8 * 4/19
380/152= 2.5 or 2 1/2
To solve this question, you want to try to get the variable alone on one side.
So, your starting equation is 7a-3=3+6a. You want to subtract 6a from both sides of the equation, so that the variable a is only on the left side of the equation.
So, after subtracting, your equation looks like a-3=3. Next, you want to add 3 to both sides, to cancel out the -3 on the left side of the equation.
If performed correctly, your equation should be a=6.
Your final answer is a=6.
In the instructions it states ABC is reflected over line BA. So the rigid transformation is "a reflection across the line containing BA"

Step-by-step explanation:
It is easier to construct the center using a compass and straightedge (and pencil). The center is where the medians meet. A median is drawn from a vertex to the midpoint of the opposite side.
A ruler can be used. It is easier if it combines full- and half-scale markings on the same edge. This will let you find the midpoint of a side quickly.
With a compass and straightedge, the usual process of constructing the bisector of a line segment is used.
