The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 se

aniked [119]

52 - 38 is 14
since on the second they sold one more child ticket then the first day we know the extra money is the price of a child ticket
so 14 is how much a child ticket is
if 3 senior citizen tickets but 14$ = 38
subtract 14 from38 = 24
and then 24/3 =senior ticket
child:14$
senior:8$

2x^2=4+6x<br> Show your work please

Furkat [3]

Answer: x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

Step-by-step explanation:

2x^2 = 4 + 6x

divide both sides by 2

x^2 = 2 + 3x

move expression to the left

x^2 - 2 - 3x = 0

reorder the terms

x^2 - 3x - 2 = 0

use the quadratic formula

x = - (-3) +- sqrt (-3)^2 - 4 x (-2) / 2 x 1

calculate

x = 3 +- sqrt 17 / 2

answer

x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

What is the explicit rule for this geometric sequence? 4,45,425,4125,…

gregori [183]

You did not write the question correctly but I will try to answer the question according to 2 possible interpretations of your question.

Case 1:

Given the geometric sequence:

$4,\ \frac{4}{5} ,\ \frac{4}{25} ,\ \frac{4}{125} ,\ .\ .\ .$

Common ratio is given by $r= \frac{2nd\ term}{1st\ term} = \frac{ \frac{4}{5} }{4} = \frac{1}{5}$

The explicit rule of a geometric sequence is given by $T_n=ar^{n-1}$

Therefore, the explicit rule of the given sequence is $T_n=4\left( \frac{1}{5} \right)^{n-1}\ or\ 20\left( \frac{1}{5} \right)^n$

Case 2:

Given the geometric sequence:

$4,\ 4\cdot5,\ 4\cdot25,\ 4\cdot125,\ .\ .\ .$

Common ratio is given by $r= \frac{2nd\ term}{1st\ term} = \frac{4\cdot5}{4} = 5$

The explicit rule of a geometric sequence is given by $T_n=ar^{n-1}$

Therefore, the explicit rule of the given sequence is $T_n=4(5)^{n-1}\ or\ \frac{4}{5}(5)^n$

Pls solve this question

EleoNora [17]

Answer:

Step-by-step explanation:

(A+B+C+D) / 4 = 10 .... average=sum/number of item

(A+B+C)/3 = 3D ... average of first 3 (A,B,C) is triple of forth (D)

A+B+C = 9D

(9D+D)/4=10

10D = 40

D = 4
