Step-by-step explanation:

So what you want is to find out what n's value is. To do that, you'll have to have n on ONE SIDE of the equation. Let's start by moving -40 to the opposite side (remember to flip the signs), making it 4n=-14n+14+40. Now, combine like terms. 14+40= 54. Now you have 4n=-14n+54. Let's go ahead and move -14n to the other side to have n in one side of the equation as mentioned before... leaving us with 14n+4n=-26. Combine like terms again. 14n+4n= 18n. Now we have 18n= 54. To get the final result, we need to have n by itself, meaning get rid of the 18 infront of it. Because they're one term, we have to divide it by 18 to have n by itself and also divide 54 by 18. Remember what you do to one side with multiplication or division, you do to the other. 54/18 = 3. Therefore, n = 3.

Answer:

$946$

Step-by-step explanation:

we know that

The formula to find the sum is equal to

$S=(a1+an)n/2$

where

a1 is the first term

an is the last term

n is the number of terms

In this problem we have

$n=11$

$a1=(98-2(1))=96$

$an=(98-2(11))=76$

substitute the values in the formula

$S=(96+76)(11/2)=946$

A high school service club is collecting

Misha Larkins [42]

We are looking for he total number of cans so:

day 1= 325 cans

day 2-9 = 944 (118 cans each day)...

118*8 = 944

therefore total number of cans =

day 1 + days 2-9

= 325+944

=1269

Bryan has a square parcel of land that is 120 yards long and 120 yards wide. The land is planted with Bermuda grass and surround

Verizon [17]

The perimeter without the diagonal is 4*120 = 480
That covers the outside of the field

The diagonal is 120 * $\sqrt{2}$ = 169.7 yd

480 + 169.7 = 649.7 yd total of fencing

The cost C (in dollars) of producing x DVD players is represented by C = 4.5x2. How many DVD players are produced if the cost is

lisabon 2012 [21]

Given the following equation representing the cost of producing DVD Players:

$\text{ C = 4.5x}^2$

Let's determine the number of DVD players produced if the cost is $544.50

$\text{ C = 4.5x}^2$ $\text{ \$544.50 = 4.5x}^2$ $\text{ }\frac{\text{\$544.50}}{\text{ 4.5}}\text{ = }\frac{\text{4.5x}^2}{\text{ 4.5}}$ $\text{ 121 = x}^2$ $\text{ }\sqrt{\text{121}}\text{ = }\sqrt{\text{x}^2}$ $\text{ 11 = x}$

Therefore, it'll cost $544.50 to produce 11 DVD Players.

The answer is 11.
