The variables x and y vary directly. Use the values to find the constant of proportionality, k. Then write an equation that relates x and y.
y=72; x=3
Answers
y = kx
Replace y and x to solve for k:
72 = 3k
Divide both sides by 3:
k = 24
Now replace k with 24:
y = 24x
The proportionality constant [tex]k=\frac{1}{24}[/tex], and the equation that relates [tex]x[/tex] and [tex]y[/tex] is [tex]x=\frac{1}{24}y\text{ or } y=24x[/tex]
Since [tex]x[/tex] and [tex]y[/tex] are related by direct proportion,
[tex]x \text{ }{\displaystyle \propto}\text{ }y \implies x=ky[/tex]
where [tex]k[/tex] is our proportionality constant. To find the value of [tex]k[/tex], substitute the values [tex]x=3\text{ and } y=72[/tex] into the formula, and solve for [tex]k[/tex].
[tex]x=ky\\\implies 3=72k\\\implies k=\frac{1}{24}[/tex]
Thus the equation that relates [tex]x[/tex] and [tex]y[/tex] is
[tex]x=\frac{1}{24}y\text{ or } y=24x[/tex]

Marcy split her income from last week equally between paying her student loans, rent, and savings. She put $300 in savings. How much did
Marcy earn last week?
?/3 =
Marcy earned $___ last week
Answers
Answer:
x/3 == 300
Marcy earned $900 last week.
Step-by-step explanation:
For this problem let's consider that 3 equal parts, or "split her income from last week equally" is 3 parts of her entire paycheck.
So she put $300 into savings which is x/3, if we let x represent the amount in dollars of her entire paycheck.
Then we can say the following:
If x / 3 == $300, then x == $900.
x / 3 == 300
( x / 3) * 3 == 300 * 3
( x * 3 / 3 ) == 300 * 3
x == 300 * 3
x == 900
So you can say the following:
x/3 == 300
Marcy earned $900 last week.
Cheers.
X=300
so Marcy earned $300

Step-by-step explanation:
Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900. The following table shows the number of sales each salesman had during the first three weeks of this month.
WEEK 1 2 3
Salesman A 11 14 16
Salesman B 14 15 13
Salesman C 16 12 11
In which week(s), did Salesman C have a larger paycheck than both of the other salesmen? Select all that apply.
Week 3
None of the weeks.
Week 2
Week 1
Answers
Answer:
Only Week 1
Step-by-step explanation:
We know that Salesman C only earns $900, no matter how many sales he makes, so we can just ignore his data for the rest of the problem. This also tells us that both Salesmen A and B have to earn less than $900 each week. That being said, let's start with Salesman A;
Now Salesman A makes $65 per sale, with no base salary, and can't go over $1,300. So starting with the first week, we do 11 sale x $65 (per means multiply) which gives us $715. Then you just repeat for weeks 2 and 3, giving us $910 week 2, and $1040 week 3. Since Salesman C made less than Salesman A for both weeks 2 and 3, we now only need to check week 1 for Salesman B.
Salesman B has a base salary of $300, and gets $40 per sale. So that means we have to do (14 sales x $40) + $300= $860. We don't need to check weeks 2 and 3, but if you wanted to, you would get $900 for week 2 and $840 week 3.
Knowing all of this, the only week Salesman C made more than BOTH Salesmen A and B is week 1, since Salesman A made more than Salesman C weeks 2 and 3, and Salesman B made more than Salesman C in week 2.

The first one is $1.19 for each balloon.
Second one is 7 months.
Step-by-step explanation:
1. 19.63 - 12.49 = 7.14 < (the cost of all six balloons) 7.14 divided by 6 = $1.19
2. 1,250 - 65 = 1,185 - 65 = 1,120 - 65 = 1,055 - 65 = 990 - 65 = 925 - 65 = 860 - 65 = 795 You had to subtract 65 each month 7 times to get less then 800.

Now addthe numerators and the whole numbers. Remeber, the denominator stays the same number, 8.

a negative plus a negative will always be a negative. Think of it as pouring 3 negatives and 4 negatives into a pot. You would just end up with 7 negatives
subtract 23-11 to get 12.
Answer:
The first one is -4 and the second one is 12. all you will need to do is change the + to a - then do for the first one which would be -7- -3= -4 so to check it you will need to use the + to check it so it will be -3+-4=-7. and for the second one you will need to do -11- -23=12 so to check it you will need to change the - to + so it will be set up as 12+ -23=-11.
