Which expression can you substitute in the indicated equation to solve the system below 5x+y =8 x+4y=2

Answer: Median 38 / Mean 24.5

Step-by-step explanation:

The median is 38

and

The mean is 24.5

To find the median just find the number in the middle of an odd set

but if it happens to be an even number add the 2 middle numbers together and divide them by 2

To find the Mean add all of the numbers and divide them by the number of sets ( in this instance its 4 )

Answer:

Step-by-step explanation:

Given function is,

y = x + 4.5

To complete the input-output table given in the picture we will substitute the values of x in the function rule,

For x = 1,

y = 1 + 4.5

y = 5.5

For x = 3

y = 3 + 4.5

y = 7.5

Therefore, complete table will be,

x         0          1          2         3        

y        4.5       5.5      6.5      7.5

Answer:

The number is 42.

Answer: A. 241 feet

Step-by-step explanation:

The figure shows two rectangular triangles.

These triangles are similar since they have two identical angles:

the first angle is 90 degrees;

the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.

The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.

Let's make the proportion:

[tex]\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\[/tex]

It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:

341.25 - 100 = 241.25 (feet)

241.25 ≈ 241 (feet)

Answer:

84

Step-by-step explanation:

100-point test = 50 questions which are worth 2-points each.

(50 x 2 = 100)

If she got 8 wrong, this means she lost 16 points ( 8 questions x 2 points each = 16 points in total)

100 - 16 = 84

To find her score if she got x questions wrong just multiply x by 2 and subtract the answer to 100.

Answer:

y = x + 3 is the Green Line

y = -1/2x -3  is the Blue Line

Answer:

188.4

Step-by-step explanation:

because if you multiply 15.7 and 12 you get 188.4 and that is the area of the jumping space.

Answer:

area = length×wide=15.7×12=188.4ft²

Answer:

Angle DCB is Equal to 78

Step-by-step explanation:

4x+2 + 3x+3 =180

7x +5=180

7x=175

x=25.

Then put the x in the 3x+3

3(25) +3 = 78

so  DCB = 78

Answer: 26%

Step-by-step explanation:

The formula to calculate the percentage markup is given as:

= Selling price - Cost / Cost price × 100

where selling price = $15750

Cost price = $12500

Percentage markup = ($15750 - $12500) / $12500 × 100

= $3250/$12500 × 100

= 26%

Answer: 26

Step-by-step explanation:

12,500 - 15,750= 3250

Answer:

yes

Step-by-step explanation:

The distributive property of multiplication over additions is:

a(b + c) = ab + ac

You multiply the number outside the parentheses, the a, by each of the numbers inside the parentheses, the b and the c. Then you add the products.

Now we can do it with your example.

-5(x + 8)

We multiply -5 by x and multiply -5 by 8. Then we add the products and simplify.

-5(x + 8) = -5 * x + (-5) * 8 = -5x + (-40) = -5x - 40

Answer: yes

Answer:

=>(4x+14)+(5x-1)+(4x-5)+(2x+7) = 360°

=>4x + 14 + 5x - 1 + 4x - 5 + 2x +7 = 360°

=>15x + 15° = 360°

=>15x = 360°- 15°

=>x = 345/15

=>x = 23

So move to K

Answer:

2

Step-by-step explanation:

Look at the ones place (1). Look to the right of it (8). Since 8 is more than 4, raise the 1 to the next number, 2. So rounded to the nearest whole number, the decimal 1.823 is 2.

Answer:

Area of the sector = 78.54 square meters

Step-by-step explanation:

Radius of the given circle = 10 meters

Sector bounded by the arc having measure = 90°

Angle subtended by the arc at the center = 90°

Area of the sector = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]

Here angle θ is the angle at the center subtended by the arc.

If angle θ = 90°

Therefore, area of the sector = [tex]\frac{90}{360}(\pi)(10)^{2}[/tex]

                                                = 25π

                                                = 78.54 square meters
