Answer:
D
F
Step-by-step explanation:
Parallel lines are lines of equal distance apart (equidistant), that are on the same plane but they never meet
Perpendicular lines meet thus they are not parallel lines
Also, lines that intersect , meet, thus they are not parallel lines
4 because you make 6 into a fraction which is 6/1. So, 2/3 x 6/1 = 12/3 = 4
Answer: Each chlorine has 7 valence electrons.
Step-by-step explanation: Chlorine is an element with atomic number 17 and thus contains 17 electrons. Valence electrons are the electrons which are present in the valence shell.
Electronic configuration of chlorine:
Chlorine atom has 7 valence electrons (2 in 3s and 5 in 3p orbital) and thus need to share one electron with other chlorine atom to complete its octet and attain stability.
Problem 1
<h3>Answer:
x = 8</h3>
----------------------------------
Explanation:
The tickmarks say that TU and UV are the same length. Both are 23 units each. They combine to TU+UV = 23+23 = 46, which is the length of TV
TV = 5x+6
TV = 46
5x+6 = 46
5x = 46-6
5x = 40
x = 40/5
x = 8

Problem 2
<h3>Answer: QR = 53 </h3>
----------------------------------
Explanation:
We use the same idea as the previous problem.
PQ = 6x-1 is the same length as QR
PQ+QR = (6x-1)+(6x-1) = 12x-2 = PR
Since PR = 15x-29, we can then say,
PR = 12x-2
15x-29 = 12x-2
15x-12x = -2+29
3x = 27
x = 27/3
x = 9
From there,
- PQ = 6x-1 = 6(9)-1 = 53
- QR = 53 since PQ and QR are the same length
- PQ+QR = 53+53 = 106
- PR = 15x-29 = 15(9)-29 = 135-29 = 106
This shows that PQ+QR = PR is true and it helps confirm the answer.
