Answer:
x = 26
Step-by-step explanation:
The parallel lines are Line l and Line m. The other line shown is the transversal.
When 2 parallel lines are cut by a trasversal it creates 4 euqual angles and another 4 equal angles of different measure.
The angle "5x + 7" is equal to the angle "8x - 71" since they are <em><u>alternate exterior angles.</u></em>
<em><u /></em>
So, we can equate both expressions and use algebra to solve for "x". The process is shown below:
![5x+7=8x-71\\8x-5x=71+7\\3x=78\\x=\frac{78}{3}\\x=26](https://tex.z-dn.net/?f=5x%2B7%3D8x-71%5C%5C8x-5x%3D71%2B7%5C%5C3x%3D78%5C%5Cx%3D%5Cfrac%7B78%7D%7B3%7D%5C%5Cx%3D26)
Hence,
the value of x is 26
Answer:
Additive
-2 = 2
18 = -18
-30 = 30
2/5 = -2/5
Multiplicative
8/9 = 9/8
12/15 = 15/12
-6 = -1/6
10 = 1/10
Step-by-step explanation:
an<em> additive inverse</em> is a number you must add to another number to get 0
(think of it as the negative version of the number)
<em>{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}</em>
-2 + 2 = 0
18 - 18 = 0
-30 + 30 = 0
2/5 - 2/5 = 0
a <em>multiplicative inverse</em> is a number that you multiply by another number to get 1.
We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction
(reciprocal of 2 = 1/2 {remember, 2 is the same thing as 2/1 } ; reciprocal of 1 / 8 = 8)
<em>note: reciprocal is being used interchangeably with multiplicative inverse here</em>
<em />
8/9 · 9/8 = 1
12/15 · 15/12 = 1
-6 · -1/6 = 1 {-6 = -6/1}
10 · 1/10 = 1 {10 = 10/1}
hope this helps!! have a lovely day :)
