Answer:
x = t(a+p)/4
Step-by-step explanation
Given the expression
a=4x/t - p
We are to make x the subject of the formula
a=4x/t - p
Add p to both sides
a+p = 4x/t - p+p
a+p = 4x/t
Cross multiply
t(a+p) = 4x
Rearrange
4x = t(a+p)
Divide both sides by 4
4x/4 = t(a+p)/4
x = t(a+p)/4
Answer:
She should have multiplied by 10,000.
Slope intercept form is y = mx + b
7 tickets for $5 means that 1 ticket costs 5/7 dollars
So for part a, the slope intercept form would be:

where x is the number of tickets, and y is the price.
For part b)
The slope intercept form is:

where x is the number of all you can ride wristbands you buy, and y is the total price.
Answer:
Proportional relationship.
Step-by-step explanation:
From the given table, let us find the ratio of each pair of time and distance.
The first pair is 2 and 90.
Therefore, the ratio is 
The second pair is 3 and 135.
Therefore, the ratio is 
The third pair is 5 and 225.
Therefore, the ratio is 
The fourth pair is 6 and 270.
Therefore, the ratio is 
Since, the ratio of each pair is same and equal to 45, therefore, the relationship is proportional relationship.
