Answer:
u= -4
Step-by-step explanation:
-36=9u
u=-36/9
u=-12/3
u=-4
Let’s go with 7.0 that is what I think it is
The solution set -18 and 0 are the true values of the absolute value equation
The absolute value equation that has the a solution set of -18 and 0 is |x + 9| = 9
<h3>How to determine the absolute value equation?</h3>
From the figure, the solution sets of the absolute value equation are given as:
x = {-18, 0}
Calculate the mean of the solution set
Mean = 0.5 * (-18 + 0)
Mean = -9
Calculate the difference of the solution set divided by 2
Difference = (0 + 18)/2
Difference = 9
The absolute value equation is the represented as:
|x - Mean| = Difference
Substitute known values
|x + 9| = 9
Hence, the absolute value equation that has the a solution set of -18 and 0 is |x + 9| = 9

Answer:
144 tickets.
Step-by-step explanation:
So first we have to take the total amount of tickets sold and divide that by 3 (because students bought 2/3 of those tickets and adults bought 1/3 of those tickets). So we get the answer of 144. So that means that the adults bought 144 tickets and the students bought 288 tickets.
Simply add -560 and -750 (remember same sides add and keep, different signs subtract) you should get -1310
