Answer:
x = 2
Step-by-step explanation:
1. Divide both sides by 2
2 (x + 3) ÷ 2 = 10 ÷ 2
2. Simplify
x + 3 = 5
3. Subtract 3 from both sides
x + 3 - 3 = 5 - 3
4. Simplify
x = 2
Using proportions, it is found that the coordinates of the other end of the fence are (-1,-7).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The midpoint of a segment is the <u>mean of the coordinates</u> of the endpoints, hence:
x + 8 = 7
x = -1.
y + 5 = -2.
y = -7.
The coordinates of the other end of the fence are (-1,-7).

Answer:
Step-by-step explanation:
We already have our equation, which is 0.80s = 6.00
This means that in this problem, we must find what the s variable is.
All you really have to do is divide 6.00 by .80.
0.80(7.5) = 6.00
