You and a friend went to the movies.You spent half your money on tickets. Then you spent 1/4 of the money on popcorn, $2 on cand

bagirrra123 [75]

Answer:

We took $ 24 to the movies.

Step-by-step explanation:

Let total money be

On movies = Half of the money = $\frac{x}{2}$

On popcorn = $\frac{x}{4}$

on candy = $2

On soda = $3

total money spent = $\frac{x}{2}$ + $\frac{x}{4}$ + 2+3+1

x = $\frac{x}{2}$ + $\frac{x}{4}$ + 2+3+1

x- $\frac{x}{2}$ - $\frac{x}{4}$ = 6

$\frac{x}{1}$ - $\frac{x}{2}$ - $\frac{x}{4}$ =6

$\frac{4x-2x-x}{4} = 6\\ \frac{x}{4} =6\\x =24$

Which is the additive inverse of the complex number -8+3i?

lawyer [7]

The additive inverse of a complex z is a complex number $-z,$ so that

$\mathsf{z+(-z)=-z+z=0+0i=0}$

Finding $-z:$

$\mathsf{z=-8+3i}\\\\\\ \mathsf{z+(-z)=0+0i}\\\\\ \mathsf{-8+3i+(-z)=0+0i}\\\\ \mathsf{-z=0+0i+8-3i}\\\\ \mathsf{-z=(0+8)+(0i-3i)}\\\\ \boxed{\begin{array}{c}\mathsf{-z=8-3i} \end{array}}\qquad\checkmark$
