Hi Brainiac

3x-y-3z for x=-2 , y=1 and z=-2

3(-2)-1-3(-2)

= -6-1-3(-2)

= -7 - 3(-2)

= -7 - (-6)

= -7+6

= -1

I hope that's help :)

Chad gets an annual salary of 25,000. He and his family spend 3500 per year on food. What percent of his salary is spent on food

Advocard [28]

Answer:

$\frac{x}{100}$ x 25000 = 3500

$x$ x 250 = 3500

x = 3500/250

x = 350/25

x = 14%
