Answer:

320 x 0.08 = X

In the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.

Step-by-step explanation:

Given that a major credit card company requires monthly payments equal to or greater than 8% of the total balance, and a consumer has a credit card balance of $ 320, the following calculations must be performed to determine an inequality that represents acceptable payment amounts:

320 x 0.08 = X

25.6 = X

Thus, in the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.

Answer:  x   = √28

Step-by-step explanation:

a² + b² = c²         Use Pythagorean Theorem to find the missing length.  

x² + 6² = 8²      

x²+ 36 = 64         [Subtract 36 from both side]  

        x²= 28        

     √x² = √28     [solve the square root from both side]

       x   = √28  

Given:

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,

and (6q – 9) centimeters.

To find:

The expression that represents the perimeter, in centimeters, of the triangle.

Solution:

We know that, perimeter of a triangle is the sum of its all sides.

[tex]Perimeter=(6p-7)+(7p-2)+(6q-9)[/tex]

Combining like terms, we get

[tex]Perimeter=(6p+7p)+6q+(-7-2-9)[/tex]

[tex]Perimeter=(13p)+6q+(-18)[/tex]

[tex]Perimeter=13p+6q-18[/tex]

Therefore, the perimeter of the triangle is represented by the expression [tex]13p+6q-18[/tex] centimeters.

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters, and (6q – 9) centimeters.

To find:

The expression that represents the perimeter, in centimeters, of the triangle.

Answer:

-18+13p+6q

12=3x

_____

3     3

x=4

Answer:

Step-by-step explanation:

You need to know the formula for the perimeter of a rectangle. We won't use it right away, but it is pertinent information.

P = 2 ( l + w )

Now, we know that the fencing costs $15.00 per foot, and that the length is 19.50 feet.

We first need to find the price of one "length" side of the fence.

To do this, multiply 19.50 by 15.00

19.50 x 15.00 = 292.5

Next, we look at the perimeter equation to see what we can plug in where.

P = 2 ( l + w )

We can put in the total price of the fencing for the yard as P, and the amount of one length side of the fence as l.

945.00 = 2 ( 292.5 + w )

And now, we simply solve for w.

945.00 ÷ 2 = ( 2 ( 292.5 + w ) ) ÷ 2

472.5 = 292.5 + w

472.5 - 292.5 = 292.5 + w - 292.5

w = 180

It costs $180 for one "width" side of the fence.

To find out how many feet that is, we do the opposite of what we did with the length. Instead of multiplying by $15.00, we divide by $15.00

$180.00 ÷ $15.00 = 12

The width of Claire's backyard is 12 feet.

Answer:

Step-by-step explanation:

In order for us to be able to find our answer, we need to show our work.

-3(x-y=3) → -3x + 3y = -9

                 +2x - 3y = -1

____________________________

                  -1x = -10

                   -1      -1

We need to divide -1 both sides in order for us to be able to find our x-value but there's more to this than just solving for X.

x = 10

x - y = 3

10 - y = 3

-10       -10

_________________

-y = -7

-1     -1

We need to divide -1 both sides in order for us to be able to find our y-value. Please note that each y is equivalent to an invisible 1.

y = 7

As a result, your answer will be B.

Answer:

DE=24

Step-by-step explanation:

We can see clearly that the two angles, angle A and angle F are congruent with one another, and since they are, we know the two triangles are shifted in a growth, not in an adjustment of angles. the hypotenuse doesnt matter, what does matter is the 5 and the 10, clearing showly the transition of Triangle ABC to Triangle DEF is times 2. Therefore, 12 times 2 is 24.

Answer:

Step-by-step explanation:

segment DE is what we want to find

notice that the two triangles are similar, similar here just means one is an exact copy of the other, except for scale.  One is an exact scale copy of the other.  sooooo  we can make some scaling of one side of one.. to the same side of the other.    here we want DE so .. see that BC is the same side on the other , smaller triangle?

now notice AB on the small triangle and FE on the bigger one... sooo just by observation we can see, that the bigger triangle is 2X bigger than the small one  ,  b/c  5 * 2 = 10  .  5 is the AB side of the smaller triangel and 10 is the same side but on the bigger triangle and 2 is our scaling factor.. got it?

So do the same on BC to find DE

12 * 2 = DE

24 = DE

Answer:

  D.  h(x) = 5x² +12x +9

Step-by-step explanation:

The final constants are mostly different, so you can simplify your work by just figuring that one.

  h(x) = g(x) -f(x)

  h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D

__

If you want to figure the whole expression ...

  h(x) = g(x) -f(x)

  h(x) = 12x² +7x -7 -(7x² -5x -16)

  h(x) = 12x² +7x -7 -7x² +5x +16

  h(x) = (12 -7)x² +(7 +5)x +(-7 +16)

  h(x) = 5x² +12x +9 . . . . . matches choice D

Answer:

-8/9

Step-by-step explanation:

Let the number = x

Expressing the problem Mathematically ;

2x * 3 = 5x - 8/9

6x = 5x - 8/9

6x - 5x = - 8/9

x = - 8/9

Hence, the number is - 8/9

Answer:

(12x+5)(x+4)

Step-by-step explanation:

Answer:

He would factor out 4(x+5)

Step-by-step explanation:

You can't do much until the 4(x+5) is factored out.

Once it is then it'd be 3x-8=4x+20

Then you subtract 3x on both sides and subtract 20 on both sides.

You'd be left with -28=x

Answer:

8

Step-by-step explanation:  

x=average

(x+x+x+x)/4=average

to increase x by 2 you add 2

x+2=average

(x+2+x+2+x+2+x+2)=4=(4x+8)/4=x+2

you'd have to increase the sum by 8 to make the numbers' averages' go up by 2
