-c +6z = tz+83
add c to each side
6z = tz +83 +c
subtract tz from each side
6z-tz = c+83
factor out z
z(6-t) = c+83
divide by (6-t)
z = (c+83)/(6-t)
Answer:z = (c+83)/(6-t)
x is 
<u>Explanation:</u>
Given:
EP = FP
GQ = FQ
Since the sides are equal, the ΔFPQ and ΔFEG are similar.
According to the property of similarity:

On substituting the value:

Perimeter will be sum of all the sides. If y is known then substitute the value and then find the perimeter.
Answer:
B. 
Step-by-step explanation:
Let n be the number.
We are asked to write an mathematical expression for the given word phrase.
One third of a number, n, would be
.
Two more than one third of a number, n, would be
.
We are told that Two more than one-third of a number is 8. We can represent this information in an equation as:

Therefore, option B is the correct choice.
Answer:
2.5 dB/100 ft
Explanation:
If 5 dB was lost after 200 ft of cable and 100 ft is half of 200 ft, then the rate of loss should be 2.5 dB per 100 ft.
