Answer:

$45927/4096$

Step-by-step explanation:

Given is the geometric series, because the ratio of consecutive terms is common:

$r = 84/112 = 63/84 = 3/4$

The first term is 112.

So the nth term is:

$t_n = t_1*r^{n-1}$

The 9th term is:

$t_9 = 112*(3/4)^8=45927/4096$

Find the solution for this system of equations. 2x − 3y = 2 x = 6y − 5

IRINA_888 [86]

Answer:

y = 4/3

x = 2

Step-by-step explanation:

2x − 3y = 2

x = 6y − 5

x - 6y = -5

2x − 3y = 2 | ×1 |

x - 6y = -5 | ×2 |

2x − 3y = 2

2x - 12y = -10

____________--

9y = 12

y = 12/9

y = 4/3

2x − 3y = 2

2x - 3(4/3) = 2

2x - 4 = 2

2x = 2 + 4

2x = 6

x = 6/3

x = 2

Solve for the value of p dont ask for ang information cuz that is literally all it says

seraphim [82]

Answer:

p = 35

Step-by-step explanation:

( 2p + 5 ) + ( 3p ) = 180

2p+5+3p=180

Combine 2p and 3p to get 5p.

5p+5=180

Subtract 5 from both sides.

5p=180−5

Subtract 5 from 180 to get 175.

5p=175

Divide both sides by 5.

p = 175\5

Divide 175 by 5 to get 35.

p = 35

(20 points!) In triangle RSW, line segment RW is a median and is equal to 27 cm. What is the length of RX?

Fofino [41]

Answer:

Option D. 18 cm

Step-by-step explanation:

we know that

A centroid of a triangle is the point where the three medians of the triangle meet.

A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

The centroid divides each median in a ratio of 2:1

In this problem the centroid of triangle RST is the point X

$\frac{RX}{XW}=\frac{2}{1}$

$RX=2XW$ -----> equation A

$RX+XW=27$ -----> equation B

substitute equation A in equation B

$2XW+XW=27$

Solve for XW

$3XW=27$

$XW=9\ cm$

Find the value of RX

$RX=2XW$ ----- $RX=2(9)=18\ cm$
