Answer:
8 because 5x4=20 then u multiply 2x4
Z - (-9) is the same as z + 9. Subtracting a negative is the same as adding.
Therefore
17 = z - (-9)
is the same as
17 = z + 9
To get 'z' all by itself, we need to subtract 9 from both sides. We subtract 9 from both sides to undo the "plus 9" occurring to the 'z' on the right side.
17 = z + 9
17-9 = z + 9=9 ... subtracting 9 from both sides
8 = z
z = 8
So the answer is z = 8
---------------------------
Check:
17 = z - (-9)
17 = 8 - (-9) ... replace z with 8
17 = 8 + 9
17 = 17
Answer checks out
Answer:
it's a scalene triangle whose all sides are different
Answer:
The correct answer should be x > -2
Step-by-step explanation:
-3(x - 3) > 5 - 5x
-3 + 9 > 5 - 5x
-3x + 5x + 9 > 5
-3x + 5x > 5 - 9
2x > 5 - 9
2x > -4
x > -2
Hope this helped! :)
