The cost of each bush is $ 18.49

Let "f" be the cost of each flower

Let "b" be the cost of each bush

Given that Mrs. Kelly buys 15 flowers and 3 bushes for a total cost of $160.32

15 flowers x cost of each flower + 3 bushes x cost of each bush = 160.32

[tex]15 \times f + 3 \times b = 160.32[/tex]

15f + 3b = 160.32  ----- eqn 1

Each bush costs $11.50 more than each flower

Cost of each bush = 11.50 + cost of each flower

b = 11.50 + f  ------ eqn 2

Let us solve eqn 1 and eqn 2 to find values of "b" and "f"

Substitute eqn 2 in eqn 1

15f + 3(11.50 + f) = 160.32

15f + 34.5 + 3f = 160.32

18f = 160.32 - 34.5

18f = 125.82

Substitute f = 6.99 in eqn 2

b = 11.50 + 6.99 = 18.49

Thus the cost of each bush is $ 18.49

By using the fact of supplement angles of congruent angles are congruent, we proved that ∠2 ≅ ∠3

Step-by-step explanation:

The supplementary angles are:

∵ ∠1 and ∠2 are supplementary

∴ m∠1 + m∠2 = 180° ⇒ (1)

∵ ∠3 and ∠4 are supplementary

∴ m∠3 + m∠4 = 180° ⇒ (2)

We can equate the left hand sides of (1) and (2) because the right hand sides are equal

∴ m∠1 + m∠2 = m∠3 + m∠4 ⇒ (3)

∵ ∠1 ≅ ∠4

∴ m∠1 = m∠4

- Substitute m∠4 by m∠1 in (3)

∴ m∠1 + m∠2 = m∠3 + m∠1

- Subtract m∠1 from both sides

∴ m∠2 = m∠3

∴ ∠2 ≅ ∠3

By using the fact of supplement angles of congruent angles are congruent, we proved that ∠2 ≅ ∠3

The interest rate is 8% simple interest.

Step-by-step explanation:

Let the investment of $555 is getting r% simple interest for 6 years to become the balance of $821.4.

So, from the equation of the simple interest we can write

[tex]821.4 = 555(1 + \frac{6r}{100})[/tex]

⇒ [tex](1 + \frac{6r}{100}) = 1.48[/tex]

⇒ [tex]\frac{6r}{100} = 0.48[/tex]

⇒ r = 8%

Therefore, the interest rate is 8% simple interest. ( Answer )

There are 6 balloons in small bouquet and 21 balloons in large bouquet.

Step-by-step explanation:

Let,

Number of balloons in small balloon bouquet = x

Number of balloons in large balloon bouquet = y

According to given statement;

2x+3y=75    Eqn 1

2x+y=33      Eqn 2

Subtracting Eqn 2 from Eqn 1

[tex](2x+3y)-(2x+y)=75-33\\2x+3y-2x-y=42\\2y=42[/tex]

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{42}{2}\\y=21[/tex]

Putting y=21 in Eqn 2

[tex]2x+21=33\\2x=33-21\\2x=12[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{12}{2}\\x=6[/tex]

There are 6 balloons in small bouquet and 21 balloons in large bouquet.

Final answer:

In solving the system of linear equations, we determined that a small balloon bouquet contains 6 balloons and a large balloon bouquet contains 21 balloons.

Explanation:

Solving a System of Equations

Let's denote the number of balloons in a small bouquet as s and in a large bouquet as l. The given problem provides us with two equations based on the information about the graduation party and Father's Day celebration:

For the graduation party: 2s + 3l = 75

For the Father's Day celebration: 2s + l = 33

Now we solve this system of linear equations to find the values of s and l. Subtracting the second equation from the first gives us:

2s + 3l - (2s + l) = 75 - 33

Which simplifies to:

2l = 42

Dividing by 2 gives us:

l = 21

Now we can plug in the value of l into any of the original equations to find the value of s. Let's use the Father's Day equation:

2s + 21 = 33

Subtracting 21 from both sides gives us:

2s = 12

Finally, dividing by 2 gives us:

s = 6

Therefore, a small balloon bouquet contains 6 balloons and a large balloon bouquet contains 21 balloons.

The value of the solution to the system of equations are, (10, - 20)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

System of equations are,

y = -5x + 30  .. (i)

x = 10

Now, We can find the solution as;

Plug x = 10 in equation (i);

y = - 5x + 30

y = - 5 × 10 + 30

y = - 50 + 30

y = - 20

Thus, The value of the solution to the system of equations are, (10, - 20)

Step-by-step explanation:

Answer:

The library is 6 blocks away to the left of Alberto's place

Step-by-step explanation:

There's missing information on this question.

Suppose the point here is to find the distance.

A reflection across the y-axis makes the y-axis as the symmetry axis.

1) Each unit represents one block and they share the same y-coordinate (4).

2) We have to subtract the absolute value of x-coordinate.

So,

[tex]|-3-(3)|=|6|=6[/tex]

The library is 6 blocks away to the left of Alberto's place.

Answer:

[tex] 3 {x}^{3} - 25 {x}^{2} + 35x - 23 = 0[/tex]

Step-by-step explanation:

We want to create an equation that will have the solution

[tex]x = \frac{1}{3},x = 4 + \sqrt{7}i,x = 4 - \sqrt{7}i[/tex]

This implies that:

[tex]3x -1= 0,x -( 4 + \sqrt{7}i) = 0,x - ( 4 - \sqrt{7}i) = 0[/tex]

We put the roots in factored form by reversing the zero product principle to get:

[tex](3x -1)(x -( 4 + \sqrt{7}i))(x - ( 4 - \sqrt{7}i)) = 0[/tex]

We expand the last two parenthesis to get:

[tex](3x - 1)( {x}^{2} - 4x + \sqrt{7}ix - 4x - \sqrt{7}ix + 16 - 7 {i}^{2}) = 0 [/tex]

We simplify to get:

[tex](3x - 1)( {x}^{2} - 8x + 23) = 0[/tex]

We expand further to obtain:

[tex]3 {x}^{3} - 25 {x}^{2} +35x - 23 = 0[/tex]

Answer:

[tex]9\ pounds[/tex]

Step-by-step explanation:

Let

x ----> the number of pounds of a DVD player

we know that

The number of pounds of a DVD player multiplied by the cost per pound ($0.55) plus the charge of $6.99 must be equal to $11.94

so

The linear equation that represent this situation is

[tex]0.55x+6.99=11.94[/tex]

solve for x

subtract 6.99 both sides

[tex]0.55x=11.94-6.99[/tex]

[tex]0.55x=4.95[/tex]

divide by 0.55 both sides

[tex]x=9\ pounds[/tex]

Answer:

x = 3

Step-by-step explanation:

Since all 3 sides of the triangle are congruent then the triangle is equilateral

We need to find the fifth term of the geometric progression

We know that the nth term formula

aₙ = a₁rⁿ-¹

where a₁ is first term and r is the common ratio

n is the number of terms

So, n = 5

a₅ = 1600

a₅ = 1600*

a₅ = 1600*81/256

a₅ =

a₅ = 506.25

Answer: $4

Step-by-step explanation:

2d + 14 = 22

subtract 14

2d = 8

divide by 2

d = $4

each bag of Doritos costs $4

Elizabeth spent a total of $8 on 2 large bags of Doritos after spending $14 on soda, which means each bag costs $4.

To determine the price of each bag of Doritos, we need to subtract the amount spent on soda from the total amount spent. Elizabeth spent $14 on soda and had a total of $22 in expenses. So, the money spent on Doritos is the difference between the total amount and the soda amount.

Amount spent on Doritos = Total amount - Amount spent on soda

Amount spent on Doritos = $22 - $14

Amount spent on Doritos = $8

Since Elizabeth bought 2 large bags of Doritos, we can find the price per bag by dividing the total amount spent on Doritos by 2.

Price per bag of Doritos = Total spent on Doritos / Number of bags

Price per bag of Doritos = $8 / 2

Price per bag of Doritos = $4 per bag

Therefore, each large bag of Doritos costs $4.

Answer:

Equation: y = 15x.

:)

Answer:

y = 15x

Step-by-step explanation:

The question asked,  what equation shows the line through the data points.  And it stated the equation needed to be in the form y = kx

Where

y represents the vertical axis

x represents the horizontal axis

k = constant

K is the constant interval and can be use to get the next points

y = kx

viewing the most visible points from the graph , let use the point where total saved is 90(y axis) and the time in weeks (x axis) is 6, the constant K can be gotten.

y = 90

x = 6

y = kx

90 = 6k

divide both sides by 6

k = 90/6

k = 15

Therefore,

y = 15x

Answer:

AC = 146

Step-by-step explanation:

Given that B  is the midpoint of AC, then

AB = BC, that is

9x + 1 = 6x + 25 ( subtract 6x from both sides )

3x + 1 = 25 ( subtract 1 from both sides )

3x = 24 ( divide both sides by 3 )

x = 8

Hence

AC = AB + BC = 9x + 1 + 6x + 25 = 15x + 26, thus

AC = (15 × 8) + 26 = 120 + 26 = 146

Answer:

146

Step-by-step explanation:

AB = BC (Definition of midpoint) so:

9x+1=6x+25.

Solve it as you would any other algebraic equation  >>>  9x+1=6x+25  >>>  9x+1-1=6x+25-1  >>>  9x=6x+24  >>>  -6x+9x=6x-6x+24  >>>  3x=24  >>>  3x/3=24/3  >>>  x=8

AB=9x+1  >>>  AB=9*8+1  >>>  AB=73

BC=6x+25  >>>  BC=6*8+25  >>>  BC=73

AC=AB+BC  >>>  AC=73+73  >>>  AC=146
