Answer:
Step-by-step explanation:
we know that
To find the conjugate complex of a complex number, simply change the sign of the imaginary part of the complex number
In this problem we have
so
the complex conjugate is equal to

Solution and Answer:
4.20 - 2.35 - $1.85 per bagel.
1.85 x 2 = $3.70 for 2 bagels.
4.20 - 3.70 = $0.50 per coffee.

7 1/4 + 5 3/5
First, you need a common denominator to add the two. 20 will work.
4x5=20, so we have to also multiply 1 by 5.
4x5=20, 1x5=5
5x4=20, so we have to also multiply 3 by 4.
5x4=20, 3x4=12
And now we put the fractions back in.
7 5/20 + 5 12/20
And add them.
7 5/20 + 5 12/20 = 12 17/20
Now, we're supposed to reduce it to its lowest form.
Unfortunately, the fraction cannot be reduced, because 17 is a prime number, meaning there are no factors to it except one and itself.
Therefore, the lowest form of 12 17/20 is 12 17/20
Your answer is B, 12 17/20
