<em>The question has missing details. However, general questions that could be asked is as follows:</em>
<em>(1) The number of miles traveled after using (say) 5 gallons</em>
<em>(2) The number of gallons used after traveling for (say) 36 miles</em>
Answer:

Step-by-step explanation:
Given
A linear equation is represented as:
Where
and
c, in this question represents the initial capacity of the tank.
So, the initial capacity is 120 liters
Solving (a): r = 5
<em>60 miles traveled</em>
Solving (b): s = 36
Collect like terms
Solve for r
<em>42 gallons used</em>
Answer:
The answer to your question is c) y = (-2/3)x + 8/3
Step-by-step explanation:
Data
A (-2, 4)
B (1, 2)
Process
1.- Calculate the slope of the line
-Formula
m = (y2 - y1)/(x2 - x1)
x1 = -2 y1 = 4 x2 = 1 y2 = 2
-Substitution
m = (2 - 4) / (1 + 2)
-Simplification
m = -2/3
2.- Find the equation of the line
Formula
y - y1 = m(x - x1)
-Substitution
y - 4 = -2/3 (x + 2)
-Simplify
y - 4 = (-2/3)x - 4/3
y = (-2/3)x - 4/3 + 4
y = (-2/3)x - 4/3 + 12/3
-Result
y = (-2/3)x + 8/3
Answer:
Step-by-step explanation:
Given:
Rosa has to skate around a face off circle five times.
Diameter of a circle = 9.0 m
Radius of a circle = 
Solution:
We know that the circumference of a circle.
Where;
r = Radius of a circle
Substitute 
in above equation.
So, the circumference of the circle is 28.26 m.
Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.
Therefore, the distance cover by Rosa to skate 141.3 m.
Answer:
Step-by-step explanation:
The small square represents a 90 degree angle. So you know 1 angle
5x + 4x + 90 = 360 because you have a circle in the center. Combine left.
9x + 90 = 360 Subtract 90 from both sides
9x = 360 - 90 Combine
9x = 270 Divide by 9
x = 270/9
x = 30
