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
--------------------------------------------------------------
Answer:
202 meters
Step-by-step explanation:
Since this is a right triangle, you can plug it into Pythagoras theorem of a squared plus b squared equals c squared. So 198 squared plus 40 squared equals 40804. Square root this and it gives you 202 meters.
Many (x,y) pairs will fit this equation
Lets let x = 12 then:-
24 = 6y - 24
6y = 48 so y = 48/6 = 8
so one ordered pair is ( 12, 8)
