Answer:
7x+3=8
Step-by-step explanation:
this is the answer
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:

Answer:
PV+=+nRT divide both sides by nR
PV/NR
Step-by-step explanation:
For this case we have to define the order of algebraic operations, that the division and multiplication must be done before (from left to right) that the addition and subtraction.
Then, given the following expression:
m = 10-6÷7-8.5
We have to:

So, we have:

We must bear in mind that equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed.
