Answer:
9
Step-by-step explanation:
All triangles (3 sided polygons) have angles added up to 180, so we can do the following:
(7x-1) + (7x+8) + (5x+2) = 180° <em>- equation</em>
7x-1 + 7x+8 + 5x+2 = 180° <em>- "distribute"</em>
19x - 1 + 8 + 2 = 180°<em> - combine the x terms</em>
19x + 9 = 180° <em>- combine the integer terms</em>
19x = 171 <em>- subtract 9 form both sides</em>
x = 9 <em>- divide both sides by 19</em>

Answer: 504.91 miles
Step-by-step explanation:
From the question, we are told that Trevon and his friends are going on a road trip that is 594 7/25 miles long and that they have 89 37/100 miles to reach their destination. To know how far that they've already traveled, we subtract 89 37/100 from 594 7/25.
= 594 7/25 - 89 37/100
Since the answer should be in decimal, we can change the fractions to decimal.
= 594 7/25 - 89 37/100
= [594 +(7/25 × 100)] - [89 + (37/100 × 100)]
= (594 + 0.28) - (89 + 0.37)
= 594.28 - 89.37
= 504.91 miles
They've already travelled 504.91 miles
