Mathematics

Answer:

u-v=-3-7i

Step-by-step explanation:

We have been given two equations u=3-4i and v=3i+6. We are asked to find the value of u-v.

Let us subtract value of v from u as:

u-v=3-4i-(3i+6)

First of all, we remove parenthesis as:

u-v=3-4i-3i-6

Now, we will combine the real part of equation with real part and imaginary part with imaginary part as:

u-v=3-6-4i-3i

u-v=-3-7i

Therefore, the value of  u-v is -3-7i.

U - v = (3 - 4i) - (3i + 6) = 3 - 4i - 3i - 6 = -3 - 7i

A local hamburger shop sold a combined total of 500 hamburgers and cheeseburgers on Wednesday. There were 50 fewer cheeseburgers
Virty [35]

Hey there! I'm happy to help!

Let's call the hamburgers h and the cheeseburgers c.

h+c=500

c=h-50

Let's plug this value for c into the first equation to solve for h.

h+h-50=500

2h-50=500

Add 50 to both sides.

2h=550

Divide both sides by 2.

h=275

Therefore, 275 hamburgers were sold on Wednesday.

Have a wonderful day! :D
