Get rid of brackets:
21x +6 +8x
Put 6 to the other side:
21x +8x = -6
27x = -6
Divide both sides by 27
X= -0.22
Answer:
3x +2x-5+(-7x+8)=
-2x+3
Step-by-step explanation:
Answer:
put a ruler in it and there it is
Speed = 225 metres per minute
Distance = 15 km = 15,000 metres
---------------------------------------------------
s=d/t
ts=d
Therefore: t=d/s
--------------------------------------------------
Time = Distance / Speed
Time = (15,000 metres) / (225 metres per minute)
--------------------------------------------------
Let's work it out:
