Answer:
3P= 3a+3b+c
3b=3a+c-3P
b= (3a+c-3P)/3
b= (3a)/3+c/3-(3P)/3
b= a+c/3-P
Step-by-step explanation:
let the expression with b be on one side of the equation while you send the other expressions to the other side of the equation.
now, divide through the equation with the coefficient of b which is 3.
simplify the equation by making b the subject of the equation

Find the equation of the line that goes through the points (12, 11) and (7,1)
Answer:
8,4
Step-by-step explanation:
Step 1: Find the slope of the line.
Step 2: Use the slope to find the y-intercept.
Step 3: Use steps 1 and 2 to write the answer.
I will explain these steps by looking a several examples. Please understand that there are often several
different ways to complete each math problem, but I have found through the years that students are most
successful when the do problems the same way each and every time they attempt the problem. If you
know a different way to find the answer that is great, but I am going to show how to do the problem one
way and use the same technique everytime I see this problem.
Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).
Step 1: Find the slope of the line.
To find the slope of the line passing through these two points we need to use the slope
formula:
( )
( )
So the slope of the slope of the line passing through these two points is 3.
Step 2: Use the slope to find the y-intercept.
Now that we know the slope of the line is 3 we can plug the slope into the equation and
we get:
y = 3x + b
Next choose one of the two point to plug in for the values of x and y. It does not matter
which one of the two points you choose because you should get the same answer in either
case. I generally just choose the first point listed so I don’t have to worry about which
one I should choose.
(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.
–2 = –3 + b Solve for b and you will have the y-intercept.
b = 1

if f(3) then ur equation would look like this f(3) = 4x - 5
then u solve it to get the answer.
3 = 4x - 5
+ 5 = 4x + 5
------------------ ---> add 5 on both sides
8 = 4x
now u just divide. 8 ÷ 4 = 2 so f(3) = 2

Jack and Jill each go out shopping.
Jack spends 1/3 of his money.
Jill spends 40% of her money.
Frank says Jack spent more because 1 /3 is greater than 40%.
Alice says you cannot tell who spent more.
Who do you agree with, Frank or Alice? Explain why.
I agree with Alice because you do not know how much money Jill and Jack had before they went shopping. If they had the same amount of money Jill would have spent more because 40 percent is greater than 1/3.

A clothing store is having a sale. A shirt normally sells for $30. The store is
offering a 15% discount. What is the discounted price?
A. $4.50
B. $25.50
C. $26.50
D. $24.50
Answer:
B. $25.50
Step-by-step explanation:
This is a bit of a trick question.
To find how much money is taken off the price, you would do 15% (0.15) • 30 and you get $4.50. This is the discount that is taken off of the price, not the discounted price. To find the new discounted price, subtract the $4.50 from $30.00.
$30.00 - $4.50 = $25.50

Write the percent as a fraction or mixed number in simplest form.
276%
Answer:when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 276/100 is also equal to 2 19/25 when expressed as a mixed number.
Step-by-step explanation:
Answer: 276/100 is also equal to 2 19/25 the expressed is a mixed number.

For a school project, Brian counts the cars every weekday after to school to determine how many are silver. He records his findings
in this table. What is the experimental probability that the next car he sees will be silver?
A 1/2
B 1/3
C 1/4
D 1/5
A)
B)
C)
D
Answer:
The correct answer is A, 14%.
Step-by-step explanation:
All you have to do is take the 30% chance of you HAVING to stop at the first light and find the chance that you won't have to stop at the first light, which is 70%, or .7. Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals .14.
