Answer:

105 degrees

Step-by-step explanation:

The sum of any quadrilateral is 360 degrees. So, in order to find x, you have to subtract all the given sides from 360.

360-100-95-60=105

The numbers given below that fall within the mean absolute deviation of the data are: C. 12,990, D. 12,705, E. 12720.

The mean absolute deviation is simply the average of the distance of each of the data points there are in a data distribution.

The difference of each data point from the mean is most likely within the same range with the mean absolute vallue.

If we subtract 12,990, 12,705, and 12720 from the mean of the data, 12,367, we would get a figure close to the mean absolute deviation, 350.

So the numbers that are within the mean absolute deviation are, C. 12,990, D. 12,705, E. 12720.

-38×+43=-40×-57

-38×+43+40=-57

-38×+40×=-57-43

2×=-57+43

2×=-100

I do not know if it's right

Given equation,

Adding 40x to both sides :

Answer:

It’s also worth pointing out that the presentation of the algebraic expressions in coin word problems are a bit different and not so straightforward compared to what we’re used to. For example, instead of saying “the number of nickels is 2 more than the number of dimes“, you’ll often see this expressed in coin word problems as “there are 2 more nickels than dimes“. Both algebraic expressions can be written in an equation as n=d+2n=d+2 but just expressed differently.

Step-by-step explanation:

Tamara has 35 coins in nickels and quarters. In all, she has $4.15. How many of each kind of coin does she have? Right off the bat, the problem gives us two important pieces of information. First, it tells us that there is a total number of 35 coins consisting of nickels and quarters. Secondly, the total value of the coins is $4.15. We need to translate these statements into algebraic equations to find how many nickels and how many quarters she has.

The solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62

Given the following function below:

f(x) = x^2 - 2
g(x) = x - 1

Since f(x) = g(x), hence;

x^2 - 2 = x - 1
x^2 - x - 1 = 0

Factorize to have:

x = 1/2 +√5/2  or x= 1/2 - √5/2

x = 1.62 or -0.62

Hence the solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62

The profit he made from selling his hearing aids at a profit of 17% is $234.26.

To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.

Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the final sale price of the earphone, we add the initial value plus the value of the profit.

$1,378 + $234.26 = $1,612.26

An equation is formed of two equal expressions. The ordered pair which is the solution of the system of linear equations is (0,2).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of the equation can be done in the following manner.

2x+3y=6

3x+5y=10

Let's take the first equation and find write it in terms of y. therefore, the first equation can be written as,

[tex]2x+3y=6\\\\2x=6-3y\\\\x = \dfrac{6-3y}{2}[/tex]

Now, substitute the value of x in the second equation,

[tex]3x+5y=10\\\\3(\dfrac{6-3y}{2})+5y=10\\\\18-9y +10y = 20\\\\-9y+10y=20-18\\\\y=2[/tex]

Thus, the value of y is 2. substituting the value of y in the first equation to get the value of x.

[tex]2x+3y=6\\\\2x+3(2)=6\\\\2x=6-6\\\\x=0[/tex]

Hence, the ordered pair which is the solution of the system of linear equations is (0,2).

The pairs of shoes increases as the time the cobbler works increases

The equation of the pairs of shoes is y = kx

The variation is a direct variation.

So, we  have:

y = kx

Where:

The cobbler can make 3 pairs of shoes in two hours,

So, we have:

k = 3/2

k = 1.5

Substitute k = 1.5 in y = kx

y = 1.5x

Hence, the equation of the scenario is y = kx

Let x = the price of movies and let y = the price of video games

8x + 3y = 43

2x + 5y = 32

Use the Elimination Method by multiplying both sides of the second equation by 4

8x + 3y = 43

-(8x + 20y = 128)

-17y = -85

y = 5

2x + 5(5) = 32

2x + 25 = 32

2x = 7

x = 7/2 = 3.5
