Answer:
It will take 6 hours to complete the biking path.
Answer : 9
Explanation:

Subtracting -5x from both sides,

Soving this quadratic equation by midterm split method,

So the roots here will be, +9 and -4.
Since the question is about only the positive value.
Your answer will be 9.
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:
(5x-1)(5x+1)
Step-by-step explanation:
In 3 hours it will be 10,300 gallons of water because add 7000 + 3300 equals 10,300
