Answer:
0.029
Step-by-step explanation:
Hello!
You solve this algebraically
4(m + 9) = -2(m - 5) + 2
Distribute the 4
4m + 36 = -2(m - 5) + 2
Distribute the -2
4m + 36 = -2m + 10 + 2
combine like terms
4m + 36 = -2m + 12
Add 2m to both sides
6m + 36 = 12
Subtract 36 from both sides
6m = -24
Divide both sides by 6
m = -4
Hope this helps!
8(2x-14)+13=4x-27
Use distribute property for the first one
16x-112+13=4x-27
16x-99=4x-27
12x=72
x=6. As a result, the value x is 6. Hope it help!
Answer:
130 meters
Step-by-step explanation:
We have to let the "surface of the ocea" be at 0 height.
So,
anything above surface has POSITIVE height
and anything below surface has NEGATIVE height
The albatross is 100 m above, so we can say its height is:
+100 meters
The shark is 30 m below, so we can say its height is:
-30 meters
The difference in height is thus:
100 - (-30) = 100 + 30 = 130 meters
