Step-by-step explanation:
Adam, Barry, and Charles visited a small farmers market last Saturday. Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes. Barry bought 1 dozen eggs and 10 pounds of potatoes, while Charles purchased 2 dozen eggs and 2 pounds of potatoes. If Adam's bill was $38.25, Barry's $36.50 and Charles' $17.20, how much did a dozen eggs, a wheel of cheese and a pound of potatoes cost?
Answer:
A pound of potato costs $3.10
A dozen egg costs $5.5
A wheel of cheese costs $6.25
Step-by-step explanation:
Represent
- a dozen egg with D
- a wheel of cheese with W
- a pound of potato with P
For Adam:
[tex]3D + W + 5P = 38.25[/tex] ---- (1)
For Barry:
[tex]D + 10P = 36.50[/tex] ---- (2)
For Charles:
[tex]2D + 2P = 17.20[/tex] ---- (3)
Make D the subject in (2)
[tex]D = 36.50 - 10P[/tex]
Substitute 36.50 - 10P for D in (3)
[tex]2(36.50 - 10P) + 2P = 17.20[/tex]
[tex]73 - 20P + 2P = 17.20[/tex]
[tex]73 - 18P= 17.20[/tex]
Collect Like Terms
[tex]- 18P= 17.20 - 73[/tex]
[tex]- 18P= -55.8[/tex]
[tex]18P= 55.8[/tex]
Solve for P
[tex]P = 55.8/18[/tex]
[tex]P = 3.1[/tex]
Substitute 3.1 for P in [tex]D = 36.50 - 10P[/tex]
[tex]D=36.50 - 10 * 3.1[/tex]
[tex]D=36.50 - 31[/tex]
[tex]D=5.5[/tex]
Substitute 3.1 for P and 5.5 for D in [tex]3D + W + 5P = 38.25[/tex]
[tex]3(5.5) + W + 5(3.1) = 38.25[/tex]
[tex]16.5 + W + 15.5 = 38.25[/tex]
Solve for W
[tex]W = 38.25 - 16.5 - 15.5[/tex]
[tex]W = 6.25[/tex]
Please help... it’s about Pythagorean theorem! I attached the image of the question
Answer:
127.28 ft
Step-by-step explanation:
Using the Pythagorean Theorem we have the following:
90^2 + 90^2 = (distance)^2
8,100 + 8,100 = (distance)^2
16,200 = (distance)^2
(distance) = (sq root sign)16, 200 = (sq root sign)25 ∗ 648 = 5 (sq root sign)36 ∗ 18
(distance)^2 = 5 ∗ 6 (sq root sign)18 = 30 (sq root sign)9 ∗ 2 = 3 ∗ 30 (sq root sign)2
(distance)^2 = 90 (sq root sign)2 = 127.28 feet

Edgar has a pen pal who uses the metric system. The pen pal wrote that his dog weighs 20 kilograms. If 1 kilogram is equivalent to 2.2 pounds, about how many pounds does the dog weigh?Required to answer. Single choice.
Answer:
44 pounds
Step-by-step explanation:
We are told that;
1kg = 2.2 pounds.
Now, the pen pal wrote that his dog weighs 20 kilograms.
Thus, the dog's weight in pounds will be gotten by proportion as;
Weight = (20 kg × 2.2 pounds)/1 kg
Weight = 44 pounds
Therefore, the dog weighs 44 pounds

Find two numbers that multiply to be 20 and add up to be -12.
Answer:
4 and -5
Step-by-step explanation:
Minus times minus equals positive, therefore, the two numbers that will give 20 when multiplied, -12 when added up are: -10 and -2.
What is Minus times MInus?As a law of operation in mathematics, when two negative numbers are multiplied, the result will always be positive. - × - = +.
Thus, we would have:
-10 × -2 = 20
-10 + (-2) = -12
Therefore, two numbers that will give 20 when multiplied, and would also add up to give -12 are: -10 and -2.

At the Gwinnett county fair, each person pays $8.99 for admission (in order to get in) plus $2.50 for each ride. While at the fair, Elian goes on six rides. Which expresion could be used to find the total amount Elian spends?
Answer:
The expression is
[tex]y=8.99+2.5x[/tex]
Step-by-step explanation:
Step one:
given data
cost per person for entry/admission= $8.99
cost per ride= $2.5
we are told that Elian went on six rides
Step two:
let the number of rides be x
the linear function for the total cost at the Gwinnett county fair for each person is
[tex]y=8.99+2.5x[/tex]
for x=6
y=8.99+2.5(6)
y=8.99+15
y=23.99
The total amount Elian spends is $23.99
What is the equation of this line in slope-intercept form?
y = 3x + 1
y = -3x - 1
y = -1/3x - 1
y = 3x - 1
Answer:
y = -3x - 1
Step-by-step explanation:
-1 is the slope intercept, as you can see where the line goes through the y-axis.
The line is also negative, as it's going down, and the slope is three down (negative) and one over. Since slope is written as y over x (y/x), 3 is y. One, the x, doesn't need to be written because 3 is already a whole number.

Write a quadratic equation in standard form with 1 over 2
and 3 as its roots
Answer:
f(x) = 2x² - 7x + 3
Step-by-step explanation:
Given the roots are x = [tex]\frac{1}{2}[/tex] and x = 3, then the corresponding factors are
(x - [tex]\frac{1}{2}[/tex] ) and (x - 3), that is
(2x - 1) and (x - 3)
The equation is then the product of the roots, that is
f(x) = (2x - 1)(x - 3) ← expand factors using FOIL
f(x) = 2x² - 7x + 3 ← in standard form
