To get the multiplicative inverse of any number, just take the reciprocal of that number.
So for 1/4, it is 4/1
= 4/1 = 4
Multiplicative inverse of 1/4 is 4.
29. d=-4
32. h=45
35. n=76
38. t=5
43. x=-11
46. x≈0.7
47. x≈1.6
49. d=-2
50. t=1/2
This is a system
x is the number of advanced tickets sold
y is the number of same day tickets sold
once you label your variables then write the equations
x+ y = 45 total tickets sold
20x + 25y = 1050 money taken in
multiply the top equation by -20 and the x will drop out
-20x - 20y = -900
20x + 25y = 1050. Add the equations result is
5y = 150, divide by 5 ,
y or same day tickets cost $30
substitute 30 into first equation
x + 30 = 45 therefore x = 15
The product of 60 and a number and sixty times a number.
