Simple,
we know that in 1 hour there are 60 minutes.
1 hr=60 min
So take, 60*5, to find 5 hours worth of minutes.
60*5=300.
So, in 5 hours, there are 300 minutes.
Answer:
335
Step-by-step explanation:
multiply it by 2 and 3 respectively
Answer:
x = -2
Step-by-step explanation:
First we have to distinguish the numbers with x from the "normal" numbers.
2x and 6x are numbers with x.
3 and 0 are "normal" numbers.
Now we have to seperate them on different sides of the equal sign.
To do this, we can subtract 3 from the left side and then add it to 0 on the left side.
Therefore, the equation will now be 2x + 6x = -3.
Now we can add 2x and 6x together, making it 8x.
The equation will now be 8x = -3.
To find the product of x, we need to divide both sides together.
So 8 divided by -3 will make -2.
Therefore, x is -2.
Hope my explination makes sense :)
