Answer:
111/20 = 5.55
Step-by-step explanation:
He used a total of 1 3/4 and 3 4/5 salt.
Convert both these mixed numbers into fractions.
=> 7/4 + 19/5
Take the LCM of the denominators
=> 35/20 + 76/20
Add the numerators
=> 111/20 = 5.55
He used a total of 111/20 or 5.55 kgs of salt.
D would equal to either 9 or -9
Answer:
y = -6x - 10
Step-by-step explanation:
(-2, 2), m = -6
Slope-intercept:
y - y1 = m(x - x1)
y - 2 = -6(x + 2)
y - 2 = -6x - 12
y = -6x - 10
The imaginary number ' i ' is the square root of -1.
i = √-1
i² = -1
i³ = -√-1
i to the 4th power = +1
i to the 5th power = √-1
etc.
and all the higher powers keep going in the same 4-step cycle.
What's 29 divided by 4 ?
It's 7 with a remainder of 1.
So 29 with all the 4s thrown away is 1, and ' i ' to the 29th power is
the same thing as ' i ' to the 1st power = √-1 or just plain ' i '.
