Answer:

x + 12 = 0

Step-by-step explanation:

Answer:

x = -12

Step-by-step explanation:

1 x 8 = 8

1 x x = 1x

1 x 4 = 4

rewrite expression

8 + 1x + 4 = 0

combine like terms

8 + 4 = 12

1x + 12 = 0

subtract 12 from both sides

12 - 12 = 0

0 - 12 = -12

1x = -12

divide by 1 on both sides to get x by itself

1x/1 = x

-12/1 = -12

Answer:

Younger: 12.78 per item

Older: 9.67 per item

Step-by-step explanation:

Well, if all the shirts and shorts were the same price divide the total price and total amount of items they bought.

Younger Brother:

8 shirts + 10 shorts = 18 items for $230

$230 ÷ 18 items = about 12.78 per item (it comes out to a lot of number so I estimated it the nearest hundredth)

Older Brother:

8 shirts + 4 shorts = 12 items

$116 ÷ 12 items = about 9.67 per item (estimated again)

Answer:

In English, we would call these terms the “Greatest Common Denominator” and the “Least Common Multiple”. It looks like in Italian at least, MCM stands for “Minimo Comune Multiplo” (aka Least Common Multiple) and MCD stands for “Maximo Comune Divisor” (aka Greatest Common Denominator).

Answer:

Step-by-step explanation:

Remark

All you need is 2 points that you can rely on as being accurate.

(2,0) should certainly be one of them. I would pick (-1,3) as the other but it is less certain.

Givens

y2 =3

y1 = 0

x2 = -1

x1 = - 2

Formula

m = (y2 - y1)/(x2 - x1)

Solution

m = (3 - 0) / (-1 - - 2)

m = (3 )/ (-1 + 2)

m = 3/1

m = 3

answer:

the equation would be

200 + ( 50 * x ) = total cost

x is variable for the number of months  

but lets use the number 2 ( 2 months ) for example

200 + ( 50 * 2 ) =

using pemdas we solve what is in the parentheses first

50 * 2

= 100

then just add the following numbers since they are the only ones left over in the problem

100 + 200

= 300

now we know that in 2 months and if you chose this cell phone plan, you will have to spend 300 dollars even!

hope this helps you and if you ever need anymore help or just not understanding this topic then please feel free to ask me! :)

and just in cause you dont know what pemdas stands for,

parentheses, exponents, multiplication/division ( always start from left to right ), addition/subtraction ( and again always start from left to right )

Answer: 4,500 milliliters of water

Answer:

It is given that,

Sin 37° = 0.602

Cos 37° = 0.790

Tan 37° = 0.754

To find:

The length of side LN.

Solution:

In a right angle triangle,

[tex]\sin\theta =\dfrac{Perpendicular}{Base}[/tex]

Using this in triangle LMN, we get

[tex]\sin (37^\circ) =\dfrac{LM}{LN}[/tex]

[tex]0.602=\dfrac{6}{LN}[/tex]

[tex]0.602LN=6[/tex]

Divide both sides by 0.602.

[tex]LN=\dfrac{6}{0.602}[/tex]

[tex]LN=9.966777[/tex]

[tex]LN\approx 9.97[/tex]

Therefore, the correct option is C.

Answer:

Cash price

Step-by-step explanation:

The computation is shown below:

The Interest rate per month (r) = (9% ÷ 12) = 0.75%

Now Present value of the monthly payment is

= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}

= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}

= 18,748.89

And the cash price is 15,999

So, the cash price would be lower

The cash price would be lower. A further explanation is below.

According to the question,

Interest rate per month,

[tex]r = \frac{9 \ percent}{12}[/tex]

  [tex]= 0.75[/tex] (%)

hence,

The Present value of the monthly payment will be:

= [tex]PMT\times \frac{{(1 + Interest \ rate)^{number \ of \ years} - 1}}{Interest \ rate}[/tex]  

= [tex]1499\times \frac{[(1 + 0.75 \ percent)^{12} - 1] }{0.75 \ percent}[/tex]  

= [tex]18748.89[/tex]

As we can see that the cash price is 15,999. Thus the above answer is right.

Answer: Make the ramp longer

making the ramp shorter and making the ramp steeper would be the same, and backing up wouldn't really help

Pickle should make the ramp longer in order to be successful.

Option A is the correct answer.

The ramp refers to a sloped surface that connects a lower level to a higher level.

We have,

- A longer ramp will provide a more gradual slope, which will make it easier for the cart to move up the ramp.

- If the ramp is too short,

The slope will be too steep and it will be difficult to push the cart up.

- Making the ramp steeper will also make it more difficult to push the cart up.

- Starting with a running start may provide some initial momentum, but it will not address the underlying problem of the ramp being too short.

Thus,

Pickle should make the ramp longer in order to be successful.
