step One
Find the total number of rocks in the gravel pit
<em>58 + 213 + 522 = 793</em>
Step Two
<em>Set up the probabilities.</em>
<em>P(Sedimentary) = 58 / 793 = 0.0731</em>
<em>P(metamorphic) = 213/ 793 =0.2686</em>
<em>P(igneous) = 522 / 793 = 0.6583</em>
Check
<em>When these are added together the answer should be one.</em>
<em>0.0731 + 0.2686 + 0.6583 = 1 just as it should.</em>
It is equilateral triangle, so the 3 sides have the same length
5x - 22 = 4x - 10
5x - 4x = -10 + 22
x = 12
The value of x is 12
Answer:
1. 2/6 or 1/3
2. 4/6 or 2/3
3. 3/6 or 1/2
Step-by-step explanation:
I hope this helps I did the ones I knew
Take your original equation 
and multiply both sides by
to remove the fractions. You are left with

So, 
Update: There is no numerical answer that can be found without being given a value for either x or y
