The product of a number and its reciprocal would be equal to one
So just flip the numbers
=32/21
Answer:
discount=MP-SP
=Rs420-Rs405
=Rs15
Step-by-step explanation:
<span>-16 - w, when w = -23
-16 - (-43) = 27</span>
39x-3y=21
-3y=21-39x
(subtract both sides of the equation by 39x and divide both sides by -3)
y=-7+3x : would be the equation for y.
R + d = 1750
r = d + 450
d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays
r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100
