Answer:
Are you in k12? Bc I failed this :(
Step-by-step explanation:
For this case we must resolve each of the inequalities and find the solution set.
Inequality 1:

We subtract 7 from both sides of the inequality:

We divide between 12 on both sides of the inequality:

Thus, the solution is given by all values of x less than
Inequality 2:

We add 8 to both sides of the inequality:

We divide between 5 on both sides of the inequality:

Thus, the solution is given by all values of x greater than
The solution set is given by:

Answer:
x=13
z=84
Step-by-step explanation:
The intersection of two of these lines actually have relationships. The two angles that have the variable x both add up to 180 degrees since we assume for them to be a straight line, and the angle with '11x-59' is equal to Z since they are vertical from each other.
Knowing this, we can add the two equations together and equal it to 180. This is to give us the variable x.
(11x-59)+(13x-73)=180 (always use parenthesis!)
24x-132=180 (combine like terms)
24x=312
x=13 (isolate x)
We now know that the x stands for 13, but we are not done. By plugging in the variable x in for the equation 11x-59, we can find the value of z since they are vertical angles.
11(13)-59=84
z=84
