Evaluate 5x-6y-7z-3x+2y-z-4x-3y+z

Mathematics
1 answer:
Mazyrski [523]3 years ago
6 0

Answer:

-2x-7y-7z

Step-by-step explanation:

I'm going to start off by separating the different variables and keeping the sign in front with it.

(5x-3x-4x) + (-6y+2y-3y) + (-7z-z+z)

After that it's simply solving a simplifying.

(-2x) + (-7y) + (-7z)

And your final answer should be...

-2x - 7y - 7z!

Hope I helped!

Andreyy89

Answer:

180 miles

Step-by-step explanation:

Going North

<em><u>Formula</u></em>

d = r * t

<em><u>Givens</u></em>

r = 60 mph

t = 5.2 hours

d = ?

<em><u>Solution</u></em>

d = 5.2 * 60 = 312 miles north

Going South

<em><u>Givens</u></em>

r = 55 mph

t = 2.4 hours

<em><u>Solution</u></em>

d = r * t

d = 55 * 2.4

d = 132

Distance from home

Formula: Distance from home = Distance North - Distance South

Distance North = 312  -   132 = 180 miles
