60% markup means 60 percent of 90 dollars added back into the price
45 is 60 percent of 90 dollars so you would add that to $90
Answer:
C. each result is equally likely to occur
Step-by-step explanation:
there's a 50% chance it'll either be heads or tails because there is only two probable options - heads or tails.
The velocity is 4. You didn’t say what you needed to find but I’m pretty sure it’s that
To solve equations like this we need to do inverse operations.
First we need to build an equation: 9+3x=21
We pass the nine to the other side, subtracting the 9 to 21, that leaves us with 3x=12
After that we just divide 12 by 3, wich gives us x=4, or, as it says in the question: n=4
Now let's double check:
N=4, since 3*4=12 and 12+9=21
Hope it is helpful :)
