The circumference of the circle is 40π. Hope it help!
First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20
Final answers:
First car=20 gallons
Second car=35 gallons
<h2>
Answer:</h2>
s = 18°
<h2>
Step-by-step explanation:</h2>
The figure has been re-labelled to show additional information and description and has been attached to this response.
As shown in the figure, line AB is a straight line.
The angles on the straight line are <em>6s + 2</em> and <em>4s - 2</em>
<em></em>
Since the sum of angles on a straight line is 180°, it therefore implies that;
<em>6s + 2</em> + <em>4s - 2 = 180°</em>
<em></em>
<em>Solve for s by collecting like terms and simplifying</em>
6s + 4s + 2 - 2 = 180
6s + 4s = 180
10s = 180
s = 18°
Therefore, the value of s is 18°
Answer: 127º
Step-by-step explanation: The sum of internal angles from a polygons is equal to 180 (n-2) where n is the number of sides for the polygon
so the polygon from the picture has 6 sides then the total sum of internal angles is:720º
On the other hand, added all the internal angles we have: 112º+133º+128º+100º+120º=593º
the angle denoted by x is equal to 720º-593º= 127º
