Answer:
3$
Step-by-step explanation:
If the chicken was 4 times the amount of potatoes you would have to divide 12 by 4 to get you answer which would be 3$
12/4 = 3
potato's = 3$
to check you answer you would do 3 times 4 and if it gives you the cost of chicken (12) then it is correct.
Answer: $3
Step-by-step explanation:
If the chicken is 4 times as much, you can divide the cost of the chicken, which is $12. So, 12 divided by 4 is 3. The potatoes cost 3 dollars.

Hillary earns $60 per week at her job, plus $2 for each item she sells. She wants to
earn at least $300 per week. Write an inequality to represent how many items, x, Hilary
must sell.
Answer:
60+2x≥300
Step-by-step explanation:
So we know that she makes a base of $60 a week and gets $2 extra for every item she sells. First, we set up an equation for how many items she would have to sell to make exactly $300 in a week. 60+2x=300. Now, all we do is replace the equal sign with a ≥ sign because it says at least which means more than or equal to.
Answer:

Hourly employees make more per week than salaried employees. C. Salaried pay. Salaried employees make more per week than hourly employees. D. There is not enough information given to compare weekly earnings. Please select the best answer from the choices provided A B C D.
We will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.
How do you find out the best salary option?
Given that, Salary per year = $78,000.
Hourly employees get paid $26 per hour, but get $39 per hour for each hour over 40 hours.
The total number of working hours from Sunday to Saturday is 47.
The payment for 47 hours of work per week will be given below.
Salary per week = [tex]40 \times 26 + 7 \times 39[/tex]
Salary per week = $1313
We know that there are 52 weeks in one year. So the salary for one year is given below.
Salary per year = [tex]1313\times 52[/tex]
Salary per year = $68276
We can see that we calculate the yearly salary with per hour rate, the amount will be lower than the salary per year $78000.
Hence we will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.

Five women were giving a friend a baby shower. They decided they would split the cost of everything evenly. The cake cost $25.50 and the gift cost $125.00. They bought 3 packages of plates for $2.75 each and 2 boxes of forks for $1.25 each. How much will each woman spend on the shower?
Answer: $ 32.25 each
Answer:
32.25$ for each woman
Step-by-step explanation:
total cost calculation
cost of plates = 3 * 2.75 =8. 25$
cost of forks = 2*1.25 = 2.50$
total cost = 125+25.50+8.25+2.5=. 161.25$
cost bore by each = 161.25/5 = 32.25$

Which polynomials are prime? Check all that apply. 2x2 7x 1 5x2 – 10x 5 3x2 8 4x2 – 25 x2 36.
You can use the definition of prime polynomials to find out which polynomial is prime and which is not.
The prime polynomials in the given options are:
Option 1: [tex]2x^2 + 7x + 1[/tex]
Option 3: [tex]3x^2 + 8[/tex]
What are prime polynomials?Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.
(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)
Which of the given polynomials are prime?Option 1: [tex]2x^2 + 7x + 1[/tex]
We have to check it manually. The roots of this equation are
not integer or integer fraction (checked from calculator), and does't factor into smaller integer coefficient polynomials.
(you can check if its getting factored, manually, and most of the times, if it is not prime, it will get factored).
Thus, it is a prime polynomial.
Option 2: [tex]5x^2 - 10x +5[/tex]
We can rewrite it as
[tex]5x^2 -10x + 5\\5x^2 - 5x -5x =5\\5x(x-1) -5(x-1)\\(5x-5)(x-1)[/tex]
Thus, it is possible to write it as product of lower degree polynomial with integer coefficients, thus it is not a prime polynomial.
Option 3: [tex]3x^2 + 8[/tex]
Since 3 is prime number and since given polynomial is quadratic thus lower degree would be only linear, thus, let
[tex](3x+a)(x+b) = 3x^2 + 8\\3x^2 + (a+3b)x + ab = 3x^2 + 8\\a = -3b\\ab = 8\\(-3b)b = 8\\b = \sqrt{-8/3}[/tex]
b is not a real number, so the factorization is not polynomial factorization.
Thus, it is prime polynomial.
Option 4: [tex]4x^2 - 25[/tex]
We can rewrite it as:
[tex](2x)^2 - 5^2= (2x+5)(2x-5)[/tex]
Thus, not a prime polynomial.
Option 5: [tex]x^2 - 36\\[/tex]
We can rewrite it as:
[tex]x^2 - 6^2 = (x-6)(x+6)[/tex]
Thus, not a prime polynomial.
Thus,

It’s due today.
Step-by-step explanation:
Data:
In this question, we're given with a line thought which two lines interest on the common point of that line. Thus, one pair of vertically opposite angles are formed here. We are also obtained with many straight lines.
In those, one straight line has been given with three measurements are 64°, 40° and 76° .
To find:
13⟩. Angle SYX
14⟩. Angle XYW
15⟩. Angle WYV
16⟩. Angle SYW
17⟩. Angle TYX
18⟩. Angle VYX
Solution:
First of all we should find all the given measurement angle vertically opposite angles, After that we can easily find the angles the question has said.
We know that the vertically opposite angles are always equal, so
Angle SYT = Angle WYV = 64°
Angle TYU = Angle XYW = 40°
Angle UYV = Angle SYX = 76°
Now,
13⟩. Angle SYX = 76°
14⟩. Angle XYW = 40°
15⟩. Angle WYV = 64°
16⟩. Angle SYW = 76° + 40° = 116°
17⟩. Angle TYX = 64° + 76° = 140°
18⟩. Angle VYX = 64° + 40° = 104°

M+6=3×D
5D=3D-6
2D=6
D=12
M=12×3=36
Now: D=12-6=6
M=36-6=30
x = daughter's age
so:
5x = 6 + 3x
5x - 3x = 6
2x = 6
x = 6/2
x = 3

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given Ellie borrows money at a year simple rate of [tex]6\frac{1}{2}[/tex]%.
After 4 years ellie owes 39 interest
We need to find how much money did ellie borrow.
Let us convert [tex]6\frac{1}{2}[/tex]% to decimal value by dividing with 100
[tex]6\frac{1}{2}[/tex]/100=6.5/100=0.065
Now we have formula for interest
I=PRT
Where I is the interest=39
P is the principle amount which we need to calculate
R is rate of interest=0.065
T is the time in years=4
Plug in these values.
39 = P x 0.065 x 4
39 = P x 0.26
Divide both sides by 0.26
150 = P
