Answer:

270 flowers total she sell Together.

Step-by-step explanation:

According to the Question,

Let, x = number of orchid bunches & y = number of rose bunches.

Therefore, 25x + 30y = 390 ⇒⇒ Equation 1  

she sells 4 times as many orchid bunches as rose bunches,

Therefore,  x = 4y  ⇒⇒ Equation 2

25 × (4y) + 30y = 390  

100y + 30y = 390

130y = 390  ⇔ y = 390 / 130 ⇒ 3  

if y = 3, then x = 4y must be equal to x= 12.

Thus, she sold 12 orchid bunches and 3 rose bunches.

Now, Each orchid bunch contains 20 flowers and each rose bunch contains 10 flowers.

Answer:

Step-by-step explanation:

The discriminant tells you where the graph of the parabola goes through the x-axis, if at all. If the discriminant is negative there are no real zeros and the parabola does not cross or touch the x-axis; if the discriminant is positive the parabola will go through the x axis in 2 places; if the discriminant is 0 the parabola will touch the x-axis in 1 place. Our discriminant is 0 since the parabola only touches the x-axis but does not go through.

the answer is 38 minutes

Answer:

18

Step-by-step explanation:

Answer:

x = 25

Step-by-step explanation:

X-7 = 18

Add 7 to each side

X-7+7 = 18+7

x = 25

Given that,

X-7 = 18

Now we can add 7 to each side,

→ X-7 + 7 = 18+7

→ x = 25

So, option (A) is the correct answer.

======================================================

Explanation:

h = number of hours past 7 pm

20h = the number of glasses sold after h hours

20h+180 = adding on the 180 glasses already sold

20h+180 > 240 is the inequality to set up

Let's solve for h

------------------

20h+180 > 240

20h > 240-180

20h > 60

h > 60/20

h > 3

They must remain open more than 3 hours past 7 pm in order to sell more than 240 glasses of juice.

The earliest that they can close is 11 pm (since 4+7 = 11).

--------------------

If h = 3, then

20h+180 = 20*3 + 180 = 240

meaning that they haven't reached their goal of getting over 240

So they have to stay open that extra hour to get past 240.

Answer:

8

Step-by-step explanation:

The median is 8 since 8 is the most common number

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 4 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , so

y = 3x + c ← is the partial equation

To find c substitute (2, 1) into the partial equation

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = 3x - 5 ← equation of parallel line → D

Answer:

$14

Step-by-step explanation:

Let Joe have $x

Then Nate would have $(x-5)

They both have $(x + (x-5)  which is equal to $43

                           $(x + x -5) = $43

                           $2x - $5 = $43

                            $2x = $(43 - 5)

                           $2x = $38

Divide both sides by $2

                               x = 19 (Joe has $19)

:. Nate has $(19 - 5) = $14.

Nate have 24 dollars.

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

Suppose that Jo has x dollars of amount, and

Nate has y dollars of the amount

Given that Jo had $5 more than Nate and together they had $43

x + 5 = y  ,

x + y = 43,

Substitute the value of y in the equation x + y = 43,

x + 5 + x = 43

2x = 43 - 5

2x = 38

Divide both sides by 2

x = 19

Now substitute the value of y = 19 in the equation x = y +5,

So, y = 19 + 5

y = 24

Hence, Nate have 24 dollars.

Answer:

A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation

Given:

The figure of a circle O.

To find:

The value of x.

Solution:

First, label some points on the given figure as shown below.

In triangle BOC,

[tex]OB=OC[/tex]                 (Radii of same circle)

It means [tex]\Delta BOC[/tex] is an isosceles triangle and the base angles of an isosceles triangles are congruent. So,

[tex]\angle OBC\cong \angle OCB[/tex]

[tex]m\angle OBC=m\angle OCB[/tex]

[tex]75^\circ=m\angle OCB[/tex]

In triangle [tex]\Delta BOC[/tex],

[tex]m\angle BOC+m\angle OBC+m\angle OCB=180^\circ[/tex]          (Angle sum property)

[tex]m\angle BOC+75^\circ+75^\circ=180^\circ[/tex]

[tex]m\angle BOC+150^\circ=180^\circ[/tex]

[tex]m\angle BOC=180^\circ-150^\circ[/tex]

[tex]m\angle BOC=30^\circ[/tex]

Now,

[tex]m\angle BOC=m\angle BOC+m\angle COD[/tex]

[tex]m\angle BOC=30^\circ+94^\circ[/tex]

[tex]m\angle BOC=124^\circ[/tex]

Using the central angle theorem, we get

[tex]m\angle BAD=\dfrac{1}{2}\times m\angle BOD[/tex]

[tex]x=\dfrac{1}{2}\times 124^\circ[/tex]

[tex]x=62^\circ[/tex]

Therefore, the correct option is B.

[tex] \large{f(x) = g(x)} \\ \large{ {x}^{2} + 3x = x + 3}[/tex]

Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.

[tex] \large{ {x}^{2} + 3x - x - 3 = 0}[/tex]

Combine like terms.

[tex] \large{ {x}^{2} + 2x - 3 = 0}[/tex]

Solve the equation by factoring.

[tex] \large{(x + 3)(x - 1) = 0} \\ \large{x = - 3,1}[/tex]

Hence the values of x that make f(x) = g(x) are -3 and 1.
