By the way, Google has a built in calculator. You can just type in "321.5 kmph in mph" and it will come up with this answer.
You could also use the fact that
,
According to the properties of equality, if you have two equal expressions and you change them in the same way, the results wil also be equal.
So that means we can multiply each side by 321.5 and get our answer above.
Answer:
One solution
Step-by-step explanation:
Lets solve it for b
3b= -6a+12
3b= 6a-12
Simplifying
b= -2a+4
b= 2a+4
Both have same slope and intercept hence both lines are going to intersect at one point. So the equations are having one solution.
Answer:
20 hours
Step-by-step explanation:
first calculate volume:
12x10x3=360
then divide by 18
360/18=20
So 20 hours in total
Solution
For this case we can do the following:
And then if we multiply we got:
