Explanation: Clearly, the teacher selects what to ask in the tests, and it is plausible to think that (s)he will select problems that they deem important.

Answer:
y=
x=
Step-by-step explanation:
7x+4+12x+24=180
19x+28=180
19x=180-28
19x=152°
19x/19=152/19
x=8
y=7x+4
y=7*8+4
y=60°
For number 5. X=12.5 and for number 6. X=4
Hope this helps :)
This is 2/3 / 1/4 = 2/3 * 4/1 = 8/3
