Answer:
v=13
Step-by-step explanation:
3(13) = 39+11 = 50
Answer:
Our main goal is to isolate the variable here (v).
And if we want to solve this equation,
we must utilize inverse operations.
Given that:-
3v + 11 = 50
We always first get rid of the constants.
And in this case, 11 is our constant.
So the inverse operation of addition is subtraction (because 11 is being added)
-11 -11
3v = 39
Now, we are left with a co-efficient.
To isolate v, we must apply the inverse operation of multiplication which is division (because 3 and 'v' are being multiplied).
/3 /3
V = 13
Eddie and Janice are buying school supplies. Eddie buys 5 notebooks and 6 binders for a total of $25.45. Janice buys 4 notebooks and 8 binders for $30.60. What is the cost of each item?
Answer:
Notebook $1.25
Binder $3.20
Step-by-step explanation:
5n + 6b = 25.45
4n + 8b = 30.6
Multiply the first equation by -4.
Multiply the second equation by 5.
Add the equations.
-20n - 24b = -101.8
20n + 40b = 153
16b = 51.2
b = 3.2
5n + 6(3.2) = 25.45
5n + 19.2 = 25.45
5n = 6.25
n = 1.25
Answer:
Notebook $1.25
Binder $3.20

A tourism agency can sell up to 1500 travel packages for the Sugar Bowl college football postseason game in New Orleans. The package includes airfare, weekend accommodations, and the choice of two types of flights: a nonstop flight or a two-stop flight. The nonstop flight airplane can carry up to 150 passengers, and the two-stop flight airplane can carry up to 100 passengers. The agency can locate no more than 12 planes for the travel packages. The tourism company makes a profit of $1100 for each non-stop flight airplane sold and $800 for each two-stop flight airplane sold. Assume that each plane will carry the maximum number of passengers.
Define the variables for this situation.
Write a system of linear inequalities to represent the constraints.
Graph the system of linear inequalities and shade the feasible region that shows the area of the graph representing valid combinations of nonstop and two-stop flight packages. Be sure to label your axes with correct increments.
Write an objective function that maximizes the revenue for the tourism agency.
Find the maximum revenue for the given constraints and give the combination of flights that achieves this maximum.
The maximum revenue would be _______________ and would be achieved using _____ nonstop flights and _____ two-stop flights.
The maximum revenue would be $9600 and would be achieved using 0 nonstop flights and 12 two-stop flights.
How to define the variablesLet x = number of non-stop airplanes
Let y = number of two-stop airplanes
The system of linear inequalitiesUsing the variables in (a), we have the following constraints
Total passenger constraint: 150x + 100y <= 1500
Total Airplanes constraint: x + y <= 12
Graph the feasible region.In (b), we have the following system of linear inequalities
150x + 100y <= 1200
x + y <= 12
See attachment for the graph
The objective functionThe objective function of the constraints is:
Max z = 1100x + 800y
The maximum revenueFrom the graph of the function, the optimal solution is:
(x,y) = (0,12)
So, the maximum revenue is:
z = 1100x + 800y
z = 1100*0 + 800*12
z = 9600
Hence, the maximum revenue is $9600

Answer:
24.3
Step-by-step explanation:
Here we need to evaluate,
[tex]\longrightarrow 3^3 +14.7\div 7-(1.2\times 4)[/tex]
First of all we need to know about BODMAS , which stands for ,
B = BracketsO = of D = divisionM = multiplicationA = AdditionS = SubtractionThis means first we need to solve brackets , then of , then division , then multiplication, then addition and finally subtraction.
In the given questions, firstly solve the terms inside the brackets ,
[tex]\longrightarrow 3^3 +14.7 \div 7 -(1.2\times 4)[/tex]
Multiply 1.2 and 4 ,
[tex]\longrightarrow 3^3+14.7\div 7-(4.8) [/tex]
Now perform division , that is divide 14.7 by 7
[tex]\longrightarrow 3^3 + 2.1 - 4.8 [/tex]
Simplify 3³ .
[tex]\longrightarrow (3)(3)(3)+2.1-4.8= 27+2.1-4.8[/tex]

Answer:
x ≈ 3.4 mm
Step-by-step explanation:
using the Sine Rule in the triangle
[tex]\frac{x}{sin27}[/tex] = [tex]\frac{7.1}{sin73}[/tex] ( cross- multiply )
x × sin73° = 7.1 × sin27° ( divide both sides by sin73° )
x = [tex]\frac{7.1sin27}{sin73}[/tex] ≈ 3.4 mm ( to 1 dec. place )
