Answer:

4x - 3y = 36

Step-by-step explanation:

⅔x-½y=6

just multiply both sides by the LCM which is 6

6×⅔x-6×½y=6×6

4x-3y=36

The solution of the given system of equations is x =1 and y = -1.

In algebra, two or more equations to be solved together (i.e., the solution must satisfy all the equations in the system). For a system to have a unique solution, the number of equations must equal the number of unknowns.

Given is a system of equations; 4x+2y=2 and y=-3x+2

Solving the equation by substitution, we get,

4x+2(-3x+2) = 2

4x-6x-4 = 2

-2x+4 = 2

-2x = -2

x = 1

Put x = 1 in any of the given equation,

y = -3*1+2

y = -3+2

y = -1

Hence, The solution of the given system of equations is x =1 and y = -1.

From the given option (1,10), (5,6) and (7,4) are ordered pairs that formed from combining a term in Pattern A with its corresponding term in Pattern B.

In the given question,

Pattern A follows the rule "add 2" and Pattern B follows the rule subtract 2

Pattern A: 1, 3, 5, 7, 9

Pattern B: 10, 8, 6, 4, 2

We have to find which ordered pairs are formed from combining a term in Pattern A with its corresponding term in Pattern B.

From the given question,

Pattern A:  1, 3, 5, 7, 9

Pattern B:  10, 8, 6, 4, 2

As given in the pattern A all numbers are 2 number up from the previous one and in pattern B each number is 2 number down from the previous one.

We have to combine a term in Pattern A with its corresponding term in Pattern B.

We have to combine with corresponding terms that means we combine one term from pattern A and one from pattern B.

Now the term after combining are

1, 10, 3, 8, 5, 6, 7, 4, 9, 2

There 6 quarters and 24 nickels of each coins that John Carlo has.

There are 5 cents in a nickel and 25 cents in a quarter. Let us represent the number of quarters as x so that the number of nickels that John Carlo has will be 4x.

Thus, 4x(5 cents) + x(25 cents) = 270 cents

20x cents + 25x cents = 270 cents

45x cents = 270 cents

divide through by 45

x = 270/45

x = 6

and thus there are 4(6) = 24 nickels.

Therefore, John Carlo has 6 quarters and 24 nickels each of coins.

A solution to a system of linear equations in two variables is an ordered pair that makes BOTH equations true.

When is the system of equations is said to be consistent?

If there is at least one combination of values for the unknowns that satisfies each equation in the system—that is, makes each equation hold true as an identity—then a system of equations, whether linear or nonlinear, is said to be consistent.

When is the system of equations is said to be non-consistent?

If there isn't a set of values for the unknowns that solves every equation, then the system of equations is said to be inconsistent.

Ex: Consider a system of linear equations:

x+3y=6                    

x=-3y+6                       …..(1)

2x+8y= -12                  …..(2)

Substitute equation (1) in (2)

2(-3y+6)+8y=-12

-6y+12+8y=-12

           2y=-24

            y=-12              ….(3)

Substitute equation (3) in (1)

x+3(-12)=6

x-36=6

x=42

Here, the order pair (x,y)=(42,-12) is the solution of the given linear equations and satisfy equations (1) and (2)

Answer:

5

Step-by-step explanation:

y=x+5 cuz it works out for everything

The value of x is 0.94 or 3.34 with the functions given.

The function is given as:

f = (x, 4 x - 17)

g = (x, (2 x + 8) / 5)

We get that:

g⁻¹ (x) = (2 x + 8) / 5

f o f (x)

= f (f (x))

= (4x [ 4x - 17] - 17)

= 16 x² - 68 x - 17

ATQ:

16 x² - 68 x - 17 = (2 x + 8) / 5

80 x² - 340 x - 85 = 2 x + 8

80 x² - 342 x - 93 = 0

Solving the equation:

D = b² - 4 ac

D = (-342)² - 4 (80) (-93)

D = 36681

x = (342 ± √36681) / 2(80)

x = (342 ± 191.52) / 160

x = 0.94 or x = 3.34

Therefore, the value of x is 0.94 or 3.34 with the functions given.

The highest possible price that a customer could have paid for their meal that evening exists $ 757. Since this is a fundraiser, $ 1 exists probably a very small amount and $757 would be considered a very generous donation for a meal.

When determining the mean (average) of a group of values, we add up the values in the group and divide that total by the number of values in the group. As a result, the average of the set's values divided by the total number of values is equal to the set's values' sum.

Let n represent how many people were in the store that evening. Thus, a total of 56n was paid that evening by all customers. The bill for the last customer's meal was $70.00. There were (n-1) customers who had already paid a total of (56n-70) dollars before this one arrived. The average cost per customer at that time was $55 dollars.

From the above information, we get

[tex]$\frac{56 n-70}{n-1} &=55 \\[/tex]

simplifying the above equation, we get

56n - 70 = 55(n - 1)

56n - 70 = 55n - 55

n = 15

Since n = 15, it follows that there were 15 customers that evening, and the total amount paid by all customers stood therefore 56 n = 56(15) = 840 dollars.

To estimate the highest possible price that a customer could have paid for their meal that evening, we will assume that 13 of the customers paid the lowest possible price of $ 1. Then the remaining customer would have paid 840 - 13 × 1 - 70 = 757 dollars.

Therefore, the highest possible price that a customer could have paid for their meal that evening exists $ 757.

Since this is a fundraiser, $ 1 exists probably a very small amount and $757 would be considered a very generous donation for a meal.

The total number of cards in a deck of cards is: 52

The total number of club cards is: 13

The total number of cards that less than 5 is: 8.

The probability of selecting a club card is,

The probability of selecting a card that is less than five is,

The total number of club card that is less than 5 is 3.

The probability of selecting a club card and a card that is less than 5 is,

The probability of selecting a card that is a club or less than 5 is,

Thus, the probability of selecting a club card or card that is less than 5 is 9/26.

The 100th term of the arithmetic sequence is 203.

Let the first term of the arithmetic sequence be a and the common difference be d.

The general term of the sequence is given by

[tex]T_{n} = a + (n-1)d[/tex]

It is given that the 6th term is 15, we have :
[tex]T_{6} = a +5d[/tex]  

a + 5d = 15......equation(1)

It is given that the 9th term is three times the 2nd term, we have :

[tex]T_{9} = 3*T_{2} \\a + 8d = 3(a +d)\\a + 8d = 3a +3d\\a -3a = 3d -8d = -5d\\-2a = -5d\\2a = 5d\\a = \frac{5d}{2}[/tex]

Putting this value in equation(1)

[tex]\frac{5d}{2} + 5d = 15 \\\\5d + 10d = 30\\15d= 30\\d = \frac{30}{15} = 2[/tex]

a = 5*2/2 = 5

Hence, the first term is 5 and the common difference is 2.

Now, evaluating the 100th term of the sequence, we have :

[tex]T_{n} = a +(n-1)d\\T_{100} = a +99d\\T_{100} = 5 +99*2 = 5 +198 = 203[/tex]

Hence, the 100th term of the arithmetic sequence is 203.

%Earns= 13% commission/week

Last week sold = $7,500

In order to obtain the last week earns in commission we need to multiply % rate of commission by the last week sold as shown as follows:

$Earns = 0.13 (decimal form)*$7,500

Earns = $975
