Find a30 of the arithmetic sequence:

−17,−7,3,13,...

Answer:

b. (4,2)

Step-by-step explanation:

step one: isolate x in the first equation

substitute x=6-y: [tex]\begin{bmatrix}2\left(6-y\right)-2y=4\end{bmatrix}[/tex]

[tex]\begin{bmatrix}12-4y=4\end{bmatrix}[/tex]

[tex]-4y=-8[/tex]

[tex]y=2[/tex]

step two: isolate y in the second equation, substitute y=2

[tex]x=6-y[/tex]

[tex]x=6-2[/tex]

[tex]x=4[/tex]

Answer:

b

Step-by-step explanation:

Given the 2 equations

3x + 3y = 18 → (2)

2x - 2y = 4 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

6x + 6y = 36 → (3)

6x - 6y = 12 → (4)

Add (3) and (4) term by term to eliminate y

12x + 0 = 48

12x = 48 ( divide both sides by 12 )

x = 4

Substitute x = 4 into either of the 2 equations and solve for y

Substituting into (1)

3(4) + 3y = 18

12 + 3y = 18 ( subtract 12 from both sides )

3y = 6 ( divide both sides by 3 )

y = 2

solution is (4, 2 ) → b

Answer:

137

Step-by-step explanation:

38 + 48 = 86

86/2 = 43

180 - 43 = 137

Answer:

127°

Step-by-step explanation:

In a quadrilateral, sum of four angles is 360°.

Consider the fourth angle x.

so,

55° + 73° + 105° + x = 360°

x = 360° - 233°

x = 127°

Answer:

1:7

Step-by-step explanation:

125:875

Then simply

The GCF between the two is 125:

125/125 = 1

875/125 = 7

So, the answer is 1:7!

100 ok this answer

Answer:

x= -1

Step-by-step explanation:

since y is -5 then we would put that in the second equation:

2x - 4(-5) = 18

then it’s:

2x + 20 = 18

Then we subtract 20 from both sides

2x = -2

Last we divide both by 2 and we get x = -1

Answer:

x= -1

Step-by-step explanation:

2x + 20 =18

2x = 18 - 20

x = -1

Given:

The length of coastline of each country in south America in thousands of kilometers.

To find:

The mean length of coastline, in thousands of kilometers

Explanation:

America is shown in thousands of kilometers so, using the given information

= 6(0) + 2(1) + 2(2) + 5(1) + 6(1) + 7(1)

= 30

= 30/15

= 2

Answer is 2 thousand kilometers

Answer:

the median is 38 and the mean is 31

Step-by-step explanation:

Answer:

Mean: 31, Median: 38

Step-by-step explanation:

Mean: 48 + 50 + 38 + 4 + 8 + 46 + 23 = 217 divided by 7 (the amount of numbers) = 31

Median: 4, 8, 23, 38, 46, 48, 50 (The middle number of the numbers in order from least to greatest)

Answer:

18617.66 ft^2

Step-by-step explanation:

sides of triangular base

a=  145ft  ,

b = 257ft ,

c =  290ft

calculate the area of the base  

The base is a scalene triangle hence the area is calculated as follows

s = ( a + b + c ) / 2

  = ( 145 + 257 + 290 ) / 2 = 346

Area of triangle = [tex]\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{346(201)(89)(56)}[/tex]

                          = 18617.66 ft^2

Answer:

x=120 (opp. angles of //gram)

Step-by-step explanation:

Because DA//CB and AB//DC (given)

Therefore ABCD is a parallelogram (opp. sides equal)

Therefore,

∠DAB = ∠DCB (opp. ∠s of //gram)

x = 120

Complete question :

Stacy has a spinner (1 - 4) and a number cube (1 - 6) after spinning and rolling the number cube she will add two number what is the probability that the sum of the numbers from the spinner and number cube will be 3 or 4

Answer:

5 /24

Step-by-step explanation:

The sample space for the sun of the outcome of the spinner and rolled number cube ;

Sample space = total possible outcomes = 6 * 4 = 24

Required outcome = sum equals 3 or 4 = 5

P(obtaining a sum of 3 or 4) = required outcome / Total possible outcomes

P(obtaining a sum of 3 or 4) = 5 /24

Answer:

Number 6 would be (a) 88 degrees

Number 7 would be (c) 45 degrees

Step-by-step explanation:

What is this Geometry? I haven't done this in so long so i went to look it up online and was shocked because of how much i was overthinking it.

For number 6, since we already have the angle listed as 44 degrees, to find the arc degrees, we would multiply the 44 by two. The formula is basically mAB=2(m<C)=88.

For number 7, we already have the arc degrees, so we would have to divide by two in this case to find the angle. The formula for this would be m<X=1/2(mYZ)=45.

Answer:

26.25 square feet

Step-by-step explanation:

Calculation to determine the area of the seat

Using this formula

Area=1/2*(b1+b2)*h

Where,

b1=8 feet

b2=7 feet

h=3.5 feet

Let plug in the formula

Area=1/2*(8+7)*3.5

Area=1/2*15*3.5

Area=26.25

Therefore the area of the seat is 26.25 square feet

Answer:

(-8, -5)

Step-by-step explanation:

If (-8, 5) is reflected across the x-axis, the x-coordinate stays the same (-8), but the y coordinate becomes -5.  Hence the coordinates of the reflection are (-8, -5).

If point (-8, 5) is reflected across the x axis, the new point is (-8, -5)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

If point (-8, 5) is reflected across the x axis, the new point is (-8, -5)
