Answer:
Total number of student tickets sold were 449.
Step-by-step explanation:
Let the number of student tickets sold = a
and the number of non student tickets = b
Total number of tickets sold = 924
So, a + b = 924 ------(1)
Students ticket costs $2 per ticket and non student ticket costs $3 per ticket and total amount collected = $2323
Therefore, the equation will be,
2a + 3b = 2323 --------(2)
Multiply equation (1) by 3 and subtract from equation (2)
(2a + 3b) - 3(a + b) = 2323 - 2772
2a - 3a + 3b - 3b = -449
-a = -449
a = 449
From equation (1)
b = 924 - a
b = 924 - 449
b = 475
Therefore, total number of student tickets sold were 449.
For this case, the first thing we must do is define variables.
We have then:
x: time in hours
y: number of total deliveries.
We have a relationship of the form:
Where,
k: slope of the line.
To find k we use the following data:
On average, I have 152 hours to make 19 successful deliveries.
Substituting values we have:
Clearing k we have:
Answer:
An unit rate that can be interpreted as the slope is:
1000 if rounded to nearest thousand
If the length is w+4 then the equation for the whole perimeter would be 4w+8. 2w+8 for both of the lengths and 2w for both of the widths.
4w+8=48
4w+8-8=48-8
4w=40
4w/4=40/4
w=10
l=10+8, l=18
l x w=a, 18*10=180
The area of the rectangle is 180in^2
