Answer:
See below in bold.
Step-by-step explanation:
a. |x| = 6
x = 6, -6.
b. |x − 5| = 4
x - 5 = 4
x = 9.
x - 5 = -4
x = 1.
c. 2|x + 3| = −10
No solution because |x + 3| is an absolute value so is always positive.

Geographic Features of Ancient Greece
Step-by-step explanation:
Greece has all these attributes on the list
~54: 1,2,3,6,9,27~
~2,754:1,2,3,6,9,17,18,27,34,51,54,81,102,153,162,
306,459, 918,1377,2754~
~27: 1,3,9,27~
GCF: 27
Your answer would be for the GCF would be 27
Answer:
523.6
Step-by-step explanation:
Following the calculation, and 3.14 for pi, the answer would be 523.6
Compatible numbers are number that are easy to add together.
If I change 87 to 90 and 34 to 30 I have compatible numbers
90 + 30 = 120. I would probably just change the 87 to 90 since I could to 90 + 34 mentally and get 124 which is closer to the exact answer.
222 + 203 - becomes 220 +200 = 420
May I suggest that you can also balance the numbers: when you change 87 to 90 you added 3. To compensate, subtract 3 from 34 and get 31. 90+31= 121, the exact answer.
222 becomes 200 so you lowered it by two. To compensate add 2 to 203. Now you have 220+205= 425 which again, is the exact answer. Use estimation is needed but what I just showed you works well to and give you the exact answer.
One more: 199 + 306 = 200 + 305 = 505 (exactly) Instead of 200 + 300 = 500 which is a close estimate using compatible numbers.
