Answer:
hey, are these two questions or one simultaneous question?
Answer: z = 7
Step-by-step explanation:
126
Explanation
18/-3-(-12)•(-1)•(-11)
divide 18 by -3 and change signs on the 12
(-6)+12•(-1)•(-11)
multiply 12 and -1
(-6)+(-12)•(-11) then multiply -11 and -12
-6+132
126
3. -17 * 3 = -51
6. 117/ -1 = -117
9. 63/ -21 = -3
12. (-3) * {7 * -2)} = -3 * -14 = 42
15. -15 * -3/ -9 = -45/-9 = 5
Hope this helps
