I want to say D, but don't take my word for it. Good luck! <3
Seeing as there are three coins, which means there are 3 heads and 3 tails.There's only a 50% chance it'll land on either side one one coin. I believe the chances to get two heads, and one tail would be somewhere around 80%, since there are only 8 possible outcomes.
Answer:
The answer to your question is This system of equations can not be solved. They do not cross.
Step-by-step explanation:
2x - 6y = 5 ----- (I)
x - 3y = -12 ----- (II)
I.- Solve equation II for x
x = 3y - 12 ------ (III)
2.- Substitute equation III on equation I
2(3y - 12) - 6y = 5
3.- Expand
6y - 24 - 6y = 5
6y - 6y = 5 + 24
0 = 29
This system of equations can not be solved.
X=31
X-23=8
Move the 23 to the right
X=23+8
X=31
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or 0.15 x $65.00=$9.75.
So, the amount of tip you are going to leave is $9.75.
This makes the total cost of your meal: $65.00 + $9.75 = $74.75.
ANSWER: $74.75
