Answer:
-6°C
-15°C
-1.5°C
Step-by-step explanation:
The computation is shown below:
in one hour the temperature falls by 3°C i.e.
= 0 - 3
= -3°C
In two hours
= 2 × - 3°C
= -6°C
In five hours
= 5 × -3°C
= -15°C
in half an hour
= 0.5 × -3°C
= -1.5°C
w-4=-12-3w
Add 12 to each side:
w + 8 = -3w
Subtract 1w from each side:
8 = -4w
Divide both sides by -4:
w = 8 / -4
w = -2
I never heard of this even in the military group that I was in, we would have gone over it if it was about swimming.
Answer:
x= -1
Step-by-step explanation:
x+5=4 or x+5= -4
