If W=20 put it in for W, Same with all the other letters: so now we have: 20+1/23+1/19+1/28. Now divide: 1/23=.043, 1/19=.053, 1/28=.036... Now add: 20+.043+.053+.036=20.132. The answer is 20.132 :)

the fifth term of an arithmetic progression is 40 and the seventh term is 28 more than the 3rd term. Find the first and 10th ter
wel

Answer:

Step-by-step explanation:

t5 = a + (5-1)d

t5 = a + 4d

40 = a + 4d

t3 = a + 2*d

t7 = a + 2d + 28 = a + 6d

Start with the seventh term which has 2 equal answers

a + 2d + 28 = a + 6d                    Subtract a from both sides

2d + 28 = 6d                                Subtract 2d from both sides

28 = 4d                                         Divide by 4

28/4 = d

d  = 7

==================

t5 = a + 4d = 40

a + 4*7 = 40

a = 40 - 28

a = 12

===================

First term is 12

10th term is

t10 = 12 + (10 - 1)*7

t10 = 12 + 9*7

t10 = 75

Interesting question. Thanks for posting

Suppose you vote in an election for a slate of candidates from a particular party.The percentage of votes the party wins in a di

These districts are best characterized as Proportional Representation districts.

What is Proportional Representation?

There are numerous types of proportional representation systems, but they all have two things in common. They start by using districts with multiple members.

Proportional Representation, abbreviated as PR, uses significantly bigger districts that elect multiple members at once, such as five or ten, rather than electing one member of the legislature in each local district. Second, the percentage of votes a party receives in these districts with several members determines which candidates gain the seats.

The Proportional Representation system of America overcomes the wide ranging drawbacks of single-district voting system like not representing the  large number of voters, discrimination against third parties, etc.

T/) The senior classes at High School A and High school B planned separate trips to the county fair.
blsea [12.9K]

Answer:

C) Van: 9, Bus: 25

Step-by-step explanation:

6V + 2B = 104

V + 2B = 59

V = 59 - 2B

6(59 - 2B) + 2B = 104

354 - 12B + 2B = 104

10B = 250

B = 25

V = 59 - 2(25)

V = 59 - 50

V = 9
