9 batches

Answer:

9

Step-by-step explanation:

25 + 25 + 25 + 25 = 100

25 + 25 + 25 + 25 = 100

+ 25

100 + 100 + 25 = 225

Answer:

3

Step-by-step explanation:

65-23= 42

42/14= 3

Answer:

14x+23 =65 x=3CDs

Step-by-step explanation:

So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.

To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.

Answer:

$P + 0.4P or 1.4P

Step-by-step explanation:

Given that:

Cost of dress pants = $P

Markup on cost price = 40%

The new retail price of a pair of dress pant :

(Cost price of the dress pant + markup on cost price)

$P + 40% of P

$P + 0.4P

New retail price = $P + 0.4P = 1.4P

Answer:

24

Step-by-step explanation:

Given:

[tex]x^2+kx-98=0[/tex]

One of the two roots of the given equation is double  the additive inverse of the other.

To find:

The value of k.

Solution:

Let two roots of the given equation are [tex]\alpha[/tex] and [tex]\beta[/tex].

According to the question,

[tex]\beta=2(-\alpha)[/tex]        (Additive inverse of [tex]\alpha[/tex] is [tex]-\alpha[/tex])

[tex]\beta=-2\alpha[/tex]

If [tex]\alpha[/tex] and [tex]\beta[/tex] are roots of the quadratic equation [tex]ax^2+bx+c=0,[/tex] then

[tex]\alpha+\beta=-\dfrac{b}{a}[/tex]

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

We have,

[tex]x^2+kx-98=0[/tex]

Here, a =1, b=k and c=-98.

[tex]\alpha+\beta=-\dfrac{k}{1}[/tex]

[tex]\alpha-2\alpha=-k[/tex]           [tex][\because \beta=-2\alpha][/tex]

[tex]-\alpha=-k[/tex]

[tex]\alpha=k[/tex]           ...(i)

Now,

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

[tex]\alpha(-2\alpha)=\dfrac{-98}{1}[/tex]          [tex][\because \beta=-2\alpha][/tex]

[tex]-2\alpha^2=-98[/tex]

Divide both sides by -2.

[tex]\alpha^2=49[/tex]

Taking square root on both sides.

[tex]\alpha=\pm \sqrt{49}[/tex]

[tex]\alpha=\pm 7[/tex]

Using (i), we get

[tex]k=\pm 7[/tex]

Therefore, the value of k is either -1 or 1.

Answer:

y = 1/2x + 5

Step-by-step explanation:

We can use point slope form since we are given a point and the slope

y -y1 = m( x-x1)

where ( x1,y1) is a point and m is the slope

y -0 = 1/2 (x- -10)

y = 1/2( x+10)

y = 1/2x + 5

Answer:

C

Step-by-step explanation:

Answer:

The y-intercept of the line is -4.

Step-by-step explanation:

y-y=m(x-x¹)

y-(-2)=-1(x-(-2))

y+2=-1x-2

-2 -2

y=-1x-4

Answer:

y=x-2

Step-by-step explanation:

the line is linear with a slope of 1/1

the y int is -2

plug into y=mx+b

y=x-2

Answer:

$4

Step-by-step explanation:

Discount is a form of consideration in price or amount given to a customer on a sale of goods. It can be deduced from the question that;

The original price of each plant = $x

Number of plants purchased = 20

Price of the number of plants purchased without discount = $20x

Amount paid for the 20 plants with discount = $(20x - 80)

Thus,

The discount on the 20 plants = $80

Discount on each plant = [tex]\frac{total discount on plants}{number of plants purchased}[/tex]

                                       = [tex]\frac{80}{20}[/tex]

                                       = $4

Discount on each plant = $4

Therefore, each plant was discounted by $4.

Answer:

solate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x<−3

Interval Notation:

(−∞,−3)

[tex]30-6x<-3(5+7x)[/tex]

Our first step is to distribute -3 in (5+7x) for easier in solving the Inequality.

[tex]30-6x<-15-21x[/tex]

Move the x-terms to the same side and constant term as well.

[tex]30+15<-21x+6x[/tex]

Moving to another side, changing the operator/sign to opposite. (Basically from Plus to Minus and Multiply to Divide)

[tex]45<-15x[/tex]

Then move -15 to divide 45. Remember, moving the negative coefficient as you have to change the sign/symbol/operator of Inequality.

[tex]\frac{45}{-15} >x[/tex]

[tex]-3>x\\x<-3[/tex]

Therefore, the answer is x < -3.

Answer:

240 copies in 30 minutes

Step-by-step explanation:

they gave us the info that it makes 40 copies in 5 minutes, divide 40/5 and you get 8, which tells us that it makes 8 copies per minute.

multiply the 8 copies that it can make in a minute by the 30 minutes, 30*8 and you get 240 copies

hope this helps :)
