Write an equation that shows the relationship between cost in dollars (y) and weight (x).

A washer and a dryer cost $847 combined. The washer costs $53 less than the dryer. What is the cost of the dryer?

Natalija [7]

--------------------------------------------------------------
Define x :
--------------------------------------------------------------
Let the dryer be x.
Dryer = x
Washer = x -53

--------------------------------------------------------------
Construct Equation :
--------------------------------------------------------------
The washer and the dryer cost $847
⇒ x + x - 53 = 847

--------------------------------------------------------------
Solve x :
--------------------------------------------------------------
x + x - 53 = 847
2x - 53 = 847
2x = 847 + 53
2x = 900
x = 450

--------------------------------------------------------------
Find cost of dryer and washer :
--------------------------------------------------------------
Dryer = x = $450
Washer = x = 450 - 53 = 397

--------------------------------------------------------------
Answer: Dryer = $450
--------------------------------------------------------------

What is the 50th term of the arithmetic sequence 3, 7, 11, 15, ... ?

zysi [14]

Answer:

B. 199

Step-by-step explanation:

We are given an Arithmetic sequence : 3, 7, 11, 15, ...

We are supposed to find the 50th term .

So, first consider the formula of nth term in Arithmetic mean:

$a_{n} = a+(n-1)*d$

where

a is first term of sequence

n is term position

d is common difference

$a_{n}$ = the term you are supposed to find

Now,

a = 3 ( first term )

n = 50 th term ( given )

d = 7-3 = 11-7 = 4(common difference

Substitute these value in the formula given above

⇒ $a_{50} = 3+(50-1)*4$

⇒ $a_{50} = 3+(49)*4$

⇒ $a_{50} = 3+196$

⇒ $a_{50} = 199$

Hence ,The 50th term of given arithmetic sequence is 199

So, OPTION B is correct .
