can someone please help me with number 18 !! :(

Answer:

answer would be 120 degrees.

Step-by-step explanation:

because 4y+4+60=180

angle Q =4y+4

so 180-60=120

Welcome to the other MHN solving classes.

Let's see what to do ......

_________________________________

Step (1)

EC bisects BED ;

Thus : BEC = CED

_________________________________

Step (2)

Question told us that CED = 4 x + 1

Thus : BEC = CED = 4 x + 1

_________________________________

Step (3)

AD is a straight line which means its angle size is equal to 180° degrees.

So :

AEB + BEC + CED = 180

( 11x - 12 ) + ( 4x + 1 ) + ( 4x + 1 ) = 180

11x + 4x + 4x - 12 + 1 + 1 = 180

19x - 10 = 180

Plus sides 10

19x - 10 + 10 = 180 + 10

19x = 190

Divided sides by 19

[tex] \frac{19}{19}x = \frac{190}{19} \\ [/tex]

[tex]x = 10[/tex]

So : x = 10°

_________________________________

Step (4)

AEB = 11x - 12

AEB = 11(10) - 12

AEB = 110 - 12

AEB = 98°

******************************************************

BEC = CED = 4x + 1

BEC = CED = 4(10) + 1

BEC = CED = 41°

_________________________________

Step (5)

AEC = AEB + BEC

AEC = 98° + 41°

AEC = 139°

Answer:

B)15.5

Step-by-step explanation:

Answer:  28

Step-by-step explanation:

Let x represent the digit in the tens place and y represent the digit in the ones place.     xy → 10x + y

The square of the sum of the digits is 100.

EQ1: (x + y)² = 100       →    x + y = 10

2 is subtracted from 3 times the number is the digits reversed.

EQ2: 3(10x + y) - 2 = 10y + x    →   30x + 3y - 2 = 10y + x      →     29x - 7y = 2

Solve the system of equations using the Elimination method:

EQ1:      x +  y = 10    →  7(x + y = 10)     →      7x + 7y = 70

EQ2: 29x - 7y = 2     →  1(29x - 7y = 2  →   29x - 7y =  2    

                                                                    36x        = 72

                                                                 ÷36         ÷36  

                                                                            x = 2

Substitute x = 2 into either of the equations to solve for y.:

EQ1: x + y = 10

       2 + y = 10

            y = 8

The digit is: 28

Answer:

y= -x + 10

Step-by-step explanation:

At 0 hours = Bob has 10 apples

At 4 hours = Bob has 6 apples

In 4 hours Bob has eaten 4 apples

Using linear graphs where y = the apples remaining and x = the hours passed

y = mx + c

We already know some coordinates:

(0,10) - 0 hours 10 apples remaining

(4,6) - 4 hours 6 apples remaining

c is the y intercept and m is the gradient

We already have the y intercept (where x = 0) which is (0,10)

So first part of our rule is done: y = mx + 10

The gradient is rise / run

Rise = -4 and Run = 4

-4/4 = -1

So the gradient is -1 and we add that to our rule

So final rule is y = -x + 10

It is 180 just do 60 times 3 since 30 times 3 is 90 and you would figure out how long it take him.

Answer:

12,500,000. You simply move the decimal point over to the right 7 times.

You will have to pay back a total of $464 over the course of the two-year loan, which includes the $400 principal plus $64 in interest.

What is Simple Interest ?

Simple interest can be defined as the ratio of product of principal amount , rate , time and hundred.

The interest on your loan can be calculated using the formula:

Interest = Principal x Rate x Time

In this case, the principal is $400, the rate is 8% (or 0.08 as a decimal), and the time is 2 years.

So, plugging in the numbers:

Interest = $400 x 0.08 x 2 = $64

Therefore, the total amount you will have to pay back is the sum of the principal and the interest, which is:

Total = Principal + Interest

= $400 + $64 = $464

Hence, You will have to pay back a total of $464 over the course of the two-year loan, which includes the $400 principal plus $64 in interest.

Answer:

25

Step-by-step explanation:

25 should be chosen as the common denominator. 5 is a possible common denominator because the other fraction has a denominator of 5 and 25 is divisible by 5, however, the numerator cannot be evenly divided by 5. Attempting to do so would cause a much more difficult equation. On the other hand, the denominator 5 can be changed to 25 by multiplying by 5, and 4 can also be changed by multiplying by 5.

4/5 x 5 = 20/25

6/25 - 20/25 = -14/20 = -7/10

Answer:

Number of hamburgers bought = 4

Number of hotdogs bought = 9

Step-by-step explanation:

Let

Number of hamburgers bought = n

Number of hotdogs bought = n + 5

Hamburgers cost = $6.25

Hotdogs cost = $3.75

Total cost = $58.75

6.25n + 3.75(n + 5) = 58.75

Open parenthesis

6.25n + 3.75n + 18.75 = 58.75

Collect like terms

6.25n + 3.75n = 58.75 - 18.75

10n = 40

Divide both sides by 10

n = 40 / 10

= 4

n = 4

Number of hamburgers bought = n = 4

Number of hotdogs bought = n + 5

= 4 + 5

= 9

Slope: undefined

Equation: x=-3

Step-by-step explanation:

To find the line that passes through the points, you first want to find the slope.  The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.

[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]

We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.

Step-by-step explanation:

Let say the unknown number we dont know is x

2x+4=6

2x=6-4

So the unknown number is 1

Answer:

-7/(x-5) - 3

Step-by-step explanation:

First off, to reflect an equation in the y axis, just multiply by -1. Now that it is reflected, to stretch an equation by a factor of 7, multiply it by 7. Now we have -7/x.

Then, to move an equation down by 3 units, simply subtract it by 3. Now we have -7/x - 3.

Lastly, since you want to translate it 5 units to the left, you want the equation to be undefined at x = 5 (because originally it is undefined at x = 0). To do that, set the denominator to x - 5. We arrive at our answer: -7/(x-5) - 3.

Using translation concepts, it is found that the new definition for the function is:

[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

----------------------------

The parent function is:

[tex]f(x) = \frac{1}{x}[/tex]

[tex]g(x) = 7 \times \frac{1}{x} = \frac{7}{x}[/tex]

[tex]g(-x) = \frac{7}{-x} = -\frac{7}{x}[/tex]

[tex]g(x) = -\frac{7}{x - 5}[/tex]

[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

Step-by-step explanation:

parallel lines have the

8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.

The slopes of parallel lines will be same.

Firstly let us find y intercept.

2=8/3(1)+b

2-8/3=b

-2/3=b

Hence, 8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.
