The sum of three numbers is 21. The second number is two more than twice the first number. The second number is three times the third number. What are the numbers?
Answer:
The numbers are:
5, 12 and 4
Step-by-step explanation:
a + b + c = 21 Eq. 1
b = 2a +2 Eq. 2
b = 3c Eq. 3
From Eq. 2:
b - 2 = 2a
(b-2)/2 = a Eq. 4
From Eq. 3:
c = b/3 Eq. 5
Replacing Eq. 4 and Eq. 5 in Eq. 1:
(b-2)/2 + b + b/3 = 21
3(b-2)/6 + 6b/6 + 2b/6 = 126/6
3(b-2) + 6b + 2b = 126
(3*b + 3*-2) + 8b = 126
3b - 6 + 8b = 126
11b = 126 + 6
11b = 132
b = 132/11
b = 12
from Eq. 4
(b-2)/2 = a
(12-2)/2 = a
10/2 = a
a = 5
from Eq. 5
c = b/3
c = 12/3
c = 4
Check:
from Eq. 1
a + b + c = 21
5 + 12 + 4 = 21

Which inequality models this problem?
Reiko started a business selling home medical supplies. She spent $6500 to obtain her merchandise, and it costs her $550 per week for expenses. She earns $900 per week for general expenses.
What is the minimum number of weeks it will take for Reiko to make a profit?
a.) 900w ≥ 6500 + 550w
b.) 900w < 6500 + 550w
c.) 900w > 6500 + 550w
d.) 550w > 6500 + 900w
Answer:
C
Step-by-step explanation:
$6500 is a one time purchase so there is no variable attached.
$550 and $900 per week is reoccurring so there will be a variable attached.
Since $900 is what she is making each week, this will be separate from her costs (can eliminate D).
To make a profit, her amount earned will need to be greater than her expenses, so the answer is C.

Order the following numbers from least to greatest 1/2, -0.67, -2/5, 0.54, -1.2
Answer:
-1.2; -0.67; -2/5; 1/2; 0.54
Step-by-step explanation:
because there are negative numbers, we put those first. the bigger the number behind the negative is, the smaller it is
-1.2 is the only negative with a ones place so it goes first
-0.67 comes right before -2/5, or -0.4
then we move into the positive numbers: 1/2 and 0.54
1/2 is 0.5, which is less than 0.54
so the order is -1.2; -0.67; -2/5; 1/2; 0.54

Both the ranges and the interquartile ranges for the data sets are the same.
Neither the ranges nor the interquartile ranges for the data sets are the same.
The interquartile ranges for the box plots are the same, but their ranges are different.
The ranges for the box plots are the same, but their interquartile ranges are different.
Answer:
to find range of interquartile sets of data
you see 5 vertical lines 1 is start point 2 is start of 2nd quartile 3 is start of 3rd quartile and also represents the median. the 4th start of 4th quartile and 5th is very end point.
Therefore the interquartile is from start line 2 to start line 4
apply to each by if it says 10 and 34 then we show workjings 34-10 = 24 and that is the range once we deduct data from each other.
Therefore full range is start line 1 to end line 5
if this says 2 to 45 then full range is 45-2 = 43 and apply to each boxplot.

Given the function f(x) = 2x, evaluate f (3).
Answer:
6
Step-by-step explanation:
Given that f(3), x=3.
Since f(x) = 2x, we plug in 3 for x, and get 2 times 3. Therefore, the answer comes out to 6.
When f(3)
Then we have:
3=2x
Now we divide by 2 (on both sides)
and are left with
x = 1.5

What is the net pay?
27.25 hours worked
$5.95 an hour
Federal tax deduction $13.29
Social Security deduction $9.65
Other deductions $6.37
$122.69
$132.83
$159.41
$162.14
Net pay for the individual is $132.83
Given that;
Number of hour worked = 27.25
Per hour pay = $5.95
Federal tax deduction = $13.29
Social Security deduction = $9.65
Other deductions = $6.37
Find:
Net pay
Computation:
Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37
Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37
Net pay = 162.1375 - 29.31
Net pay = 132.8275
Net pay = $132.83

Kathy is a scientist who is working in a remote part of Australia. She earns a salary of $86 840 plus a weekly allowance of $124.80 for working under extreme and isolated conditions. Calculate Kathy’s fortnightly pay.
Answer:
$3589.60
Step-by-step explanation:
Salary per fortnight {52 weeks in a year; 2 weeks in a fortnight}
= 86840 / 52 × 2
= 3340
Allowance per fortnight = 124.80 × 2 = 249.60
Therefore, total fortnightly pay is:
3340 + 249.60 = 3589.60

if it is a right angle triangle then;
step 1 Determine if hypotenuse or side
step 2 calculate a^2+b^2 = c^2 or c^2-b^2 = a^2 if not given hypotenuse.
if it is an obtuse or scalene triangle then
step 1. Determine the triangle third length we use trigonometry as cos (side a/sideb) to determines the angle between a and b.
With such angle for opposite side we can use sin (angle) x side to find hypotenuse or sin(angle) x hypotenuse to find side.

help me math home work part 3
Answer:9x^4
Step-by-step explanation:
6x^4*3x^3 can be simplified to 18x^7 by separating out cand combining like terms [6*3 = 18] and [x^4*x^3 = x^7]
This results in 18x^7 fr the top term
Do the same for the bottom term: 2x^2*x = 2x^3
We can now write: (18x^7)/(2x^3)
The reduces to 9x^4
