In 2 seconds it travels 160 meters
Answer:
(A) 30x+90=300
(B) $7
Step-by-step explanation:
Let x be the roller skating rink's entrance fee for one student.
So, the entrance fee for 30 students=30x
As each student pays a $3 fee to rent skates
So, the fee for rent paid by 30 students= $3x30=$90
The total cost for the students to enter the rink and rent skates= 30x+90
As given that total fee to enter the rink and rent skates is $300.
Therefore, 30x+90=300
(A) The required equation is 30x+90=300.
(B) On solving the equation, we have
Hence, the roller skating rink's entrance fee is $7.
7.5
-11 + 26 is 15. 15 divided by 2 (finding the midpoint of the two numbers) is 7.5.
Equation of the graph is y = –9x + 360.
Solution:
Take any two points on the line.
Let the points are (40, 0) and (0, 360).
Slope of the line:
m = –9
The slope is –9.
y-intercept is the point where the line intersects with the y-axis.
y-intercept = 360
b = 360
Slope-intercept form:
y = mx + b
y = –9x + 360
Equation of the graph is y = –9x + 360.
