Write an equation for the sequence whose third item is 27 and each item is 5 more than the previous.

Answers

9514 1404 393

Answer:

  an = 17 +5(n -1)

Step-by-step explanation:

The first term can be found by working backward from the third term:

  third term = 27

  second term = 22 . . . . subtract 5 from 3rd term

  first term = 17 . . . . . . . . subtract 5 from 2nd term

The generic term is given by the formula ...

  an = a1 + d(n -1) . . . . . a1 = first term; d = common difference

Here, we have a first term of 17 and a common difference of 5. So, the sequence terms are described by ...

  an = 17 +5(n -1)

Answer:

 an = 17 +5(n -1)

Tim's phone service charges $23.86 plus an additional $0.17 for each text message sent per month. If Tim's phone bill was $28.11, which equation could be used to find how many text messages, x, Tim sent last month?

A.
$23.86x + $0.17 = $28.11

B.
$0.17x - $23.86 = $28.11

C.
$0.17x + $23.86 = $28.11

D.
$23.86x - $0.17 = $28.11

GIVING BRAIN PLZ ASAP

Answers

Answer: It's C believe me

Explanation: x goes on the number that will be in this case 0.17 since it changes monthly or whatever. Then it's telling you that they already charge him 23.86 dollars so you just add it and of course 28.11 it's the total. Sry if it make sense.

The answer is C because if they charge the additional fee of 0.17 for each text they would be multiplying 0.17 for each time then adding on 23.86

A. 20 feet


B. 40 feet


C. 4,800 feet


D. 80 feet

Answers

Answer:

A. 20 ft

Step-by-step explanation:

(120/2)-40=20

Answer:

a) 20 feet

Step-by-step explanation:

We know it's a rectangle so lengths are the same and widths are the same

If length is 40

That would mean 120-2(40) = 80

We know 2 widths of a rectange so 40/2 is 20

Therefore 20 feet.

Answer:

5.4

Step-by-step explanation:

the answer is 5.4

Explanation:
3 is 3/4 of 4. this means the figure on top is 3/4 the size of the figure on the bottom. so x = 3/4(7.2)
3/4 is equal to .75, so if you multiply 7.2 by .75 (multiplying it by 3/4), you get the measure of x. in this case, x = 5.4

Answers

Answer:

x = 40°

Step-by-step explanation:

Straight angle is equal to 180°

Angle x, 60° and 80° form a straight angle.

Then we have following equation to solve for x:

x + 60° + 80° = 180°x + 140° = 180°x = 180° - 140°x = 40°
X = 40 degrees

Simplify the expression (2.5x − 5) − ((7x − 9.7)).

Answers

Answer:

−4.5x+4.7

Step-by-step explanation:

The value of the expression (2.5x − 5) − ((7x − 9.7) is 4.5x - 4.7.

In order for us to simplify the expression (2.5x − 5) − ((7x − 9.7)), we simply have to open the brackets and collect like terms. This will be:

= (2.5x − 5) − (7x − 9.7)

= 2.5x - 5 - 7x + 9.7

= 2.5x - 7x - 5 + 9.7

= -4.5x - 4.7

Therefore, the values will be 4.5x - 4.7.
