Hi there!
If the lines are parallel, Angles 1 and 2 would have to be congruent because they are corresponding angles. Therefore, to solve, all we need to do is set the values of the angles equal to each other because the angles are congruent.
WORK:
20 - 8x = 30 - 16x
-8x = 10 - 16x
8x = 10
x = 1.25
Hope this helps!! :)

Answer:
The solution of the system of equation are (10,15).
Step-by-step explanation:
The given two linear two variable equations are
- x - 2y = - 40 ........ (1) and
x + 4y = 70 .......... (2)
Now,adding thoes two equations (1) and (2) we get,
- 2y + 4y = - 40 + 70
⇒ 2y = 30
⇒ y = 15.
Now, putting y = 15 in the equation (2), we get,
x = 70 - 4y = 70 - 4(15) = 10
Therefore, the solution of the system of equation are (10,15). (Answer)

Answer:
225 minutes or 3 hours and 45 minutes
Step-by-step explanation:
45 (minutes per day) times 5 (days in a school week) = 225 minutes
or add 45 (minutes per day)+ 45+45+45+45 = 225
To get the hours:
Divide 225 by 60 (minutes per hour) and it is 3 - remainder 45.
