measure the angle of 9x+23
Answer
x= 12
Step-by-step explanation:
alternate angles right?
9x + 23 = 11x - 1
24 = 2x
x = 12
so the angle is
(11 × 12) -1
132-1

porfavor es para mañana
Answer:
A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla
entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100
en mi primera ecuación seria: 4X + 3Y = 14.100
ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla
en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:
primera ecuación: 4X + 3Y = 14.100
segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1
al sumarlas obtengo como resultado: -5X = -12
resolviendo esa ecuacion obtengo que X=
X=2.4
luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100
reemplazando seria: 4 x (2.4) + 3Y =14.100
9.6 + 3Y = 14.1000
3Y= 14.100 - 9.6
Y=
Y=1.5
entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $

7. Han's cell phone plan costs $200 to start. Then there is a $50 charge each month. a. What is the total cost (start up fee and monthly charge) to use the cell phone plan for 1 month? b. What is the total cost for x months?c.Graph the cost of the cell phone plan over a period of two years using month as the units of time be sure to label your axes and scale them by labeling each grid line with a number.d.Is there a portions relationship between time and the cost of the cell phone plan.e. Draw a line a parallel to the line you graphed that goes through the point(0,350) suppose that this line represents the pricing plan for another company.What is the startup fee and monthly cost for this plan?
Answer:
a. $250
b. The total cost for x month is $200 + $50 × x
c. Please see the attached graph
d. Yes, there is a proportional relationship between time and the cost of the cell phone plan
e. $350
Step-by-step explanation:
The given parameters are;
The costs to start on the cell phone cell = $200
The charge each month = $50
a. The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge = $200 + $50 = $250
b. The total cost for x month, c = $200 + $50 × x
c. Please see the attached graph
d. Yes, there is a proportional relationship between time and the cost of the cell phone plan
e. The line parallel to the line graphed that goes to the point (0, 350), is given as follows;
y = m·x + c
Where;
m = 50
y - 350 = 50 × (x - 0)
y = 50·x + 350
The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;
c = 50 × 0 + 350 = 350
The startup fee for the pricing plan = $350.
The startup fee and monthly cost for this plan according to the question is :
Part a:
The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge
Total Cost = $200 + $50 Total Cost = $250 The total cost to use the cell phone plan for 1 month is $250.Part b:
The total cost for x month, c = $200 + $50 × x The total cost for x month is $200 + $50 × x c.Please see the attached graph
Part c:
Yes, there is a proportional relationship between time and the cost of the cell phone plan .
Part e:
The line parallel to the line graphed that goes to the point (0, 350), is given as follows;
y = m·x + c
Where;
m = 50 y - 350 = 50 × (x - 0) y = 50·x + 350
The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;
c = 50 × 0 + 350 = 350
Yes, there is a proportional relationship between time and the cost of the cell phone plan e. $350
The given parameters are; The costs to start on the cell phone cell = $200 The charge each month = $50
The startup fee for the pricing plan = $350.

What is 35a + 14 = 1
Answer:
a = -13/35
Step-by-step explanation:
35a + 14 = 1
(given)
_________
35a + 14 = 1
- 14 -14
(subtraction property of equality)
(subtract 14 from both sides to isolate the 35a term)
_________
35a = -13
÷35 ÷35
(division property of equality)
(divide by 35 on both sides to remove the coefficient of 35 in 35a)
_________
a = -13/35
35a+14=1
35a+14 - 14 = 1 - 14
35a= -13
35a= -13
35a = -13
35 35
a= -13/35

During a special at the school book fair, each book will cost the same amount of money. Nelly can buy 4 books for $10.95. How much money will she need to buy 6 books?
Answer:
Nelly will need $16.43.
Step-by-step explanation:
First, you want to find out how much 1 book costs.
Take 10.95 and divide it by 4.
10.95/4=$2.73
Take the 2.73 and multiply it by 6.
6x2.73=16.425
=$16.43
Answer:
16.43 i think
Step-by-step explanation:
so first you divide 10.95 by 4 and get 2.74 so then you times it by 6 and get 16.43

O 16. 20), because both lines pass through this point (6. 20), because the point does not lie on any axis (3. 11), because one of the lines passes through this point (3. 11). because the point lies between the two axes
Answer:
(6,20)
Step-by-step explanation:
plug in 6 for x and 20 for y in both equations and solve.
Line c: 20 = 6 + 14
20 = 20
Line d: 20 = 3(6) + 2
20 = 18 + 2

Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Given the triangle below with centroid G, determine the following values.
If EG=3.5, then GB= and BE= If AD=15, then AG= and DG= If CG=6x, then FG- and CF=
Answer:
GB = 7
BE = 10.5
AG = 10
DG = 5
FG = 3·x
CF = 9·x
Step-by-step explanation:
The given parameters are;
The centroid of the ΔABC = G
Segments CF, BE, and AD are median lines
EG = 3.5 Given
∴ EG = 1/3 × BE by definition of the properties of median line
∴ BE = 3 × EG = 3 × 3.5 = 10.5
BE = 10.5
GB = 2/3 × BE = 2/3 × 10.5 = 7 by definition of the properties of median line BE
GB = 7
Similarly;
Given that AD = 15, AG = 2/3 × AD = 2/3 × 15 = 10 by definition of the properties of median line AD
AD = 10
DG = 1/3 × AD = 1/3 × 15 = 5 by definition of the properties of median line AD
DG = 5
Similarly;
Given CG = 6·x
FG = 1/3 × CF
CF = 3 × FG
CG = 2/3 × CF = 2/3 × 3 × FG
∴ CG = 2 × FG
FG = CG/2 = 6·x/
2 = 3·x
FG = 3·x
CF = 3 × FG = CF = 3 × 3 × x = 9·x
CF = 9·x

A pet shop sells goldfish for $ 9 per dozen. How much would 6 goldfish cost? How many goldfish could you buy with $50?
Answer:
6 goldfish = $4.50. You can buy 66 goldfish with $50
Step-by-step explanation:
We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.
To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.
We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.
