Step-by-step explanation:
The distance between the two cars is now 320 yards.
<h3 /><h3><u>
Distances</u></h3>
To determine what is the distance between the two cars now if they did not collide the following calculation must be performed:
- 500 - (500 - 405) - (500 - 415) = X
- 500 - 95 - 85 = X
- 500 - 180 = X
- 320 = X
Therefore, the distance between the two cars is now 320 yards.

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line 
The slope of the dashed line is negative
The y-intercept of the dashed line is 3
The x-intercept of the dashed line is 9
----> inequality B
The solution of the inequality B is the shaded area above the dashed line 
The slope of the dashed line is positive
The y-intercept of the dashed line is 2
The x-intercept of the dashed line is -2/3
The solution of the system of inequalities is the shaded area between the two dashed lines
see the attached figure
Answer:
$290
Step-by-step explanation:
We can use the equation that Skate Land created to find the total cost
C = 7.50p + 65
p = people so if we have 30 people, we have to solve 7.50 x 30
C = 225 + 65
we can now add the flat fee of $65 to get the total cost for the birthday part
C = $290
hope this helps :)
