Answer:

x=15

Step-by-step explanation:

As we can see, theres one traversal and two parallel lines, also we can see two angles, which the measure of is 5x+9 and 84. These two angles are alternate interior angles, and when there are alternate interior angles with parallel lines and traversal, their measures are congruent. So it would look like this.

84=5x+9

solve for x

84-9=5x

simplify

75=5x

divide by 5

15=x

Hope it helps!

Convert 0.83 into a fraction.​
Anastasy [175]

0.83 * 100 = 83, so 0.83 = 83/100.

But in case you meant the slightly more interesting repeating decimal, 0.8333...:

Let <em>x</em> denote this number. Then

10<em>x</em> = 8.333...

100<em>x</em> = 83.333...

==>  100<em>x</em> - 10<em>x</em> = 83.333... - 8.333...

==>  90<em>x</em> = 83 - 8 = 75

==>  <em>x</em> = 75/90 = 5/6
