Pentagon A B C D E is reflected across the X-axis to form pentagon A B C D.
Answer:
x = 0
Step-by-step explanation:
if 2y + x = 4
we can assume that y = 2
if y - 3x = 2
it means 2 - 0 = 2
therefore x = 0
Answer:


Step-by-step explanation:
Note that the entire segment RT is the combined lengths of RS and ST. So:

We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:

On the right, combine like terms:

Add:

Subtract 12 from both sides. The right cancels:

Divide both sides by 12:

So, the value of y is 8.
To find RS and ST, substitute 8 for y. So:

Substitute 8 for y:

Multiply:

Add:

Do the same for ST:

Substitute 8 for y:

Multiply:

Add:

Answer:
3/13
Step-by-step explanation:
First...
What we know
1. There is a set of 13 shapes.
2. With 2 triangles, 8 arrows, and circles.
Next...
Take the number of triangles and arrows and add them up.
2 + 8 = 10
Finally...
Convert it into the fraction 10/13 and subtract it by the total 13/13.
This results 3/13.
