Answer:

x= 1

y= -2

Step-by-step explanation:

1. y+3x=1 subtract 3x from both side to get y= 1-3x

2. Put the new found y value in the equation

3x-4(1-3x)=11

3. Distribute the 4

3x-4+12x=11

4. Add 4 to both sides

3x+12x=15

5. Add the x's

15x=15

6. Solve for x

x=1

7. Plug in the x in the y equation y= 1-3x

y=1-3(1)

8. Solve for y

y= -2

The solution to the system of equations is x = 1 and y = -2.

To solve the system of equations using substitution, we need to solve one of the equations for one variable in terms of the other variable and then substitute that expression into the other equation. Let's solve the second equation for y and then substitute it into the first equation:

Given system of equations:

3x - 4y = 11

y + 3x = 1

Step 1: Solve the second equation for y:

y = 1 - 3x

Step 2: Substitute the value of y from equation (2) into equation (1):

3x - 4(1 - 3x) = 11

Now, let's solve for x:

3x - 4 + 12x = 11

Combine like terms:

15x - 4 = 11

Step 3: Solve for x:

15x = 11 + 4

15x = 15

x = 15 / 15

x = 1

Step 4: Now that we have the value of x, we can find y using equation (2):

y = 1 - 3(1)

y = 1 - 3

y = -2

So, the solution to the system of equations is x = 1 and y = -2.

200/.55=364 bags i think

Elvira sells a total of 364 bags to earn a profit of $200 and this can be determined by using the unitary methods.

Given :

The following steps can be used to determine the total number of bags she sells to earn the profit of $200:

Step 1 - First find the total profit she earns to sell one bag.

= 0.90 - 0.35

= $0.55

Step 2 - Now, using the unitary method find the total number of bags she sells to earn a profit of $200 If she earns a profit of $0.55 to sell one bag.

[tex]=\dfrac{200}{0.55}[/tex]

= 363.63 [tex]\approx[/tex] 364 bags

She sells a total of 364 bags to earn a profit of $200.

Answer:

[tex]\mathbf{G(x) = (1 + x)^{29}}[/tex]

Step-by-step explanation:

From the given information;

The total number of beads  = 10 + 8 + 11 = 29

To choose k beads out 29 beads, let assume that [tex]t_k[/tex] be the no. such that:

[tex]t_k = ( ^{29}_{k}) \ \ \ where; k =0,1,2,3,....,29[/tex]

∴

The sequence [tex]\{ t_k\}^{29}_{k=0} = (^{29}_{k})[/tex]

The generating function for [tex]\{ a_k \}^n_{k=0}[/tex] is:

[tex]G(x) = a_o +a_1x +a_2x^2 +...+a_nx^n[/tex]

[tex]G(x) = \sum \limits ^{n}_{k=0} \ a_k x^k[/tex]

For the sequence above;

[tex]G(x) = \sum \limits ^{29}_{k =0 } (^{29}_{k}) x^k[/tex]

By applying binomial series [tex](1+x)^n = \sum \limits ^n_{k=0} ( ^n_k) x^k[/tex]

Thus:

[tex]\mathbf{G(x) = (1 + x)^{29}}[/tex]

18 pounds is going to be 8 times 6 which is 48

27 pounds is goings to be 8 times 9 which is 81

Answer:

2√29

Step-by-step explanation:

The value of the expression is -24.

Since the equation is [tex]4^2-5\times 2^3[/tex]

So, the value should be

[tex]= 4^2-5\times 2^3\\\\[/tex]

= 16 - 5(8)

= 16 -40

= -24

Here we use PEDMAS

P denotes for parenthesis

E denotes for exponents

D means divide

M means multiply

A means addition

S means subtraction

Therefore, we can conclude that The value of the expression is -24.

Answer:

x = 12

Step-by-step explanation:

If line r and line a are parallel, therefore:

(11x - 28) + (7x - 8) = 180° (consecutive interior angles are supplementary)

Solve for x

11x - 28 + 7x - 8 = 180

Add like terms

18x - 36 = 180

18x = 180 + 36 (addition property of equality)

18x = 216

x = 216/18 (division property of equality)

x = 12
