The algebraic form of an arithmetic sequence is 5n-2<br>a) What is its common difference?

Alexxandr [17]

Answer:

Step-by-step explanation:

[math]

U_{n} = 5n - 2 \\

Common Difference = U_{n+1} - U_{n} \\

= [5(n + 1) - 2] - [5n - 2] = [5n + 5 - 2] - [5n - 2]\\

= 5n + 5 - 2 - 5n + 2\\

= 5

Mrs. Simmons gave a history test worth 92 points. There were only two types of questions on it: 2-point true/false questions and

SVETLANKA909090 [29]

Answer:

There are 8 true/false questions and 26 fill-in-the-blank questions.

Step-by-step explanation:

Let "t" be the number of 2-point true/false questions and "f" the number of 5-point fill-in-the-blank questions.

Mrs. Simmons gave a history test worth 92 points. Symbollically,

2 t + 5 f = 92 [1]

There were a total of 34 questions in the test. Symbollicaly,

t + f = 34

t = 34 - f [2]

If we replace [2] in 1, we get

2 (34 - f) + 5 f = 92

68 - 2 f + 5 f = 92

3 f = 24

f = 8

We replace f = 8 in [2],

t = 34 - 8 = 26

There are 8 true/false questions and 26 fill-in-the-blank questions.

Determine which answer choice matches the dot plot you drew?

Vesnalui [34]

Answer:

Step-by-step explanation:

Given data are :

{1,2,2,2,2,4,4,5,6,6,8,8,8,10}

1 appears only once so there will be 1 point above number 1 in the dot plot.

Then choice B or C or D are possible choices.

2 appears 4 times so there will be 4 points above number 4 in the dot plot.

Then choice B or C or D are possible choices.

4 appears 2 times so there will be 2 points above number 2 in the dot plot.

Then choice C or D are possible choices.

5 appears once once so there will be 1 point above number 5 in the dot plot.

Only choice that satisfies those results is C.

Hence correct answer is C.

2.8y + 6 +0.2 y =5y -14

serious [3.7K]

2.8y + 6 + 0.2y = 5y - 14
(Simplify like terms in first half of equation)
3y + 6 = 5y - 14
(Subtract both sides by 3y)
6 = 2y - 14
(Flip)
2y - 14 = 6
(Add both sides by 14)
2y = 20
(Divide both sides by 2)
y=10
