Answer:
x = 17/18
Step-by-step explanation:
-5(7-8x) -7x = -(3x+1)
-35 + 40x - 7x = -3x - 1
-35 + 33x = -3x - 1
33x + 3x = -1 + 35
36x = 34
x = 34/36
x = 17/18
It would have to be number 2) x-3
The written form of the expression without negative exponents and without parentheses is; 5/x.
<h3>What is the writing form of the expression without exponents and without parentheses?</h3>
It follows from the task content that the expression can be written without parentheses and without exponents as follows;
5x-¹
= 5 × (1/x)
= 5/x
Ultimately, the written form of the expression without negative exponents and without parentheses is; 5/x.

Answer:
Step-by-step explanation:
Comment
The first step is to find the surface area of 1 fence post.
The formula is
Area_ends = 2 pi r^2 for the ends.
Area_body = 2*pi*r * h
Givens
r = d/2 r is the radius ; d is the diameter
r = 1/2 foot
h = 10 feet
Solution
1 fence post
Area = ends + area body
Area = 2*3.14 * (1/2)^2 + 2 * pi * r * h
Area = 2*3.14* (1/2)^2 + 2 * 3.14 * 1/2 * 10
Area = 1.57 + 31.4
Area = 32,97 square feet.
10 fence posts
10*32.97 = 329.7 square feet
Answer
10 fence posts have 329.7 square feet in area.
