Step-by-step explanation:if 6 can sit a a table then dividing the number of people by 6 gives the answer.
Answer:
Part A 70x+50=250
Part B(75x + 35) = 250 - 5x
Step-by-step explanation:
Here to form an equation you must add all the money that she earned and subtract the money that she had to spend We dont know how many car washes she did, so we must represent it with a variable, or x.
Subtract 60 on both sides to get -40.
You are left with 40x=-40
Divide both sides by 40 to leave x by itself.
You get x=-1.
Since we are trying to find the number of sequences can be made <em>without repetition</em>, we are going to use a combination.
The formula for combinations is:
is the total number of elements in the set
is the number of those elements you are desiring
Since there are 10 total digits, 
in this scenario. Since we are choosing 6 digits of the 10 for our sequence, 
in this scenario. Thus, we are trying to find 
. This can be found as shown:
There are 210 total combinations.
203---- 100%
x-----148%
x=203*148/100=203*1.48=300.44
