Given :
Phil sold 11 small boxes and 10 large boxes of tangerines for a total of $146.
Nick sold 5 small boxes of tangerines and 12 large boxes of tangerines for a total of $126.
To Find :
The price of each small box and large box.
Solution :
Let, price of small box is x and large box is y.
Mathematical expression of given equations :
11x + 10y = 146 ...1)
5x + 12y = 126 ...2)
Solving above equation, we get :
x = 6 and y = 8
Therefore, price of small and large box is $6 and $8 respectively.
Hence, this is the required solution.
which ordered pair is a solution of the equation: 2y=7x-3
only 2,4
only 3,9
both 2,4 and 3,9
neither
Answer:
It is only 3,9.
Step-by-step explanation:
You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:
2(9) = 7(3)-3
18= 18
The answer is (3,9).

Answer:
slope=3 y-intercept=4
Answer:
D. slope 3 y-intercept 4.
Step-by-step explanation:
The graph crosses the y-coordinate at positive 4. So we know that the y-intercept is 4, which means it cannot be A. slope 1/3. y-intercept -4, or C. slope 3 y-intercept -4.
The slope is 3, you can tell because the line ascends 3 y values for every x value gained.
This means that the answer is D. slope 3 y-intercept 4.

the antique dining table and paid 12% sales tax, how much in total did he pay?
please help if you can :)
The graph is Parabola or Graph of Quadratic Function.
The graph has minimum value, not maximum. So ( A ) is not correct for maximum part.
B is not correct for exponential part.
also C is not correct for discrete part as Quadratic graph is continuous.
So the answer is D.

How to do this question plz answer
Step-by-step explanation:
a) m∠AOB = 360°/8 = 45°
Internal angle is 360°, divided by 8 sides of octagon
b) m∠ABC = 2m∠ABO
m∠ABO = m∠BAO = 1/2(180° - 45) = 1.2(135°)
m∠ABC = 2*1/2(135°) = 135°
Answer:
a) 45
b)135
Step-by-step explanation:
[tex]In\ order\ to\ find\ the\ sum\ of\ all\ the\ interior\ angles\ of\ a\ polygon\ with\ sides\ n,\\S=180(n-2)\\Here,\\As\ the\ figure\ is\ a\ regular\ octagon\ ,\\The\ sum\ of\ all\ of\ its\ angles\ = 180(8-2)\\=180*6=1080\\Hence,\\Given\ that\ it\ is\ regular\ or\ that\ all\ of\ its\ angles\ are\ equal\ in\ measure.\\Hence,\\b) Angle\ ABC=1080/8\\=135\\As\ it\ is\ regular\ , the\ diagonals\ passing\ through\ the\ center\ bisects\ the\ respective\ angles.[/tex]Hence,
[tex]Angle OAB=135/2 = 67.5\\Angle ABO=135/2=67.5\\Through\ the\ angle\ sum\ property\ of\ a\ triangle\\Angle OAB+AngleABO+Angle AOB=180\\67.5+67.5+AngleAOB=180\\135+AngleAOB=180\\Angle AOB=180-135\\=45[/tex]

Simone paid $12 for an initial year's subscription to a magazine. The renewal rate is $7 per year. This situation can be represented by the equation y = 7x + 12, where x represents the number of years the subscription is renewed and y represents the total cost, in dollars.
Answer:
Step-by-step explanation:
Step one:
Simone paid $12 initial subscription
The rate renewable = $7 per year
let the number of years be x
and the total amount be y
the linear function/expression for the total amount is represented using the equation of line
i.e y=mx+c
where
m= gradient = $7
x= independent variable
c= constant, $12
this is also given as
y=7x+12
Step two:
let's assume the plan is for 3 years, that is x=3
then
y=7(3)+12
y=21+12
y=33
$33
For any number of years, just put x=the number of years and solve

From 1990 to 1996, the consumption of poultry per capita is modeled by: y=-.2125t^2 + 2.615t+56.33 where t=0 corresponds to 1990. What was the per capita poultry consumption in 1992?
Answer:
60.71
Step-by-step explanation:
Given that:
Consumption of poultry per capita is modeled by:
y=-.2125t^2 + 2.615t+56.33 ; t = 0 corresponds to 1990
Per capita poultry consumption in 1992;
1992 ; t = 2
y=-.2125t^2 + 2.615t+56.33
Put t = 2 in the equation
y=-.2125(2)^2 + 2.615(2) +56.33
y = -.2125(4) + 2.615(2) + 56.33
y = - 0.85 + 5.23 + 56.33
y = 60.71
solve the following quadratic equation for all value of c i'm simplest form
5(x-2)^2=20
Answer:
x=-2 and x=0
Step-by-step explanation:
5(x-2)^2 = 20; divide by 5 both sides
(x-2)^2 = 4; take the square root of both sides
(x-2) = ±2, now set it equal to positive 2 and negative 2
x-2 = 2
x=4
AND
x-2 = -2
x=0
Answer:
The values of x is 0 and 4.
Step-by-step explanation:
You have to divide 5 by both sides;
[tex]5 {(x - 2)}^{2} = 20[/tex]
[tex] {(x - 2)}^{2} = 4[/tex]
You have to expand the brackets;
[tex] {x}^{2} - 4x +4 = 4[/tex]
[tex] {x}^{2} - 4 x = 0[/tex]
You have to factorize;
[tex]x(x - 4) = 0[/tex]
Lastly, you have to solve it;
[tex]x = 0[/tex]
[tex]x = 4[/tex]

Mrs. Conley asks her class what kind of party they want to have to celebrate their excellent behavior. Out of all the students in the class,
5
55 want an ice cream party,
7 77 want a movie party,
10 want a costume party, and the rest are undecided.
If 20% percent want an ice cream party, how many students are in the class?
Step-by-step explanation:
let 'x' represent the total number of students in the class
5 = 20% of x
0.20x = 5 divide both sides by 0.20
x = 25 students
there are 25 students in the class.

What equation is being represented by this line?
Answer:
The equation that represented by the line is y = -x + 2
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given figure
∵ The line passes through points (2, 0) and (0, 2)
∴ x1 = 2 and y1 = 0
∴ x2 = 0 and y2 = 2
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{2-0}{0-2}=\frac{2}{-2}=-1[/tex]
∴ m = -1
→ Substitute it in the form of the equation above
∵ y = -1(x) + b
∴ y = -x + b
∵ b is value y at x = 0
∵ At x = 0, y = 2
∴ b = 2
→ Substitute it in the equation above
∴ y = -x + 2
∴ The equation that represented by the line is y = -x + 2
