Who's Weggy?

2x + 3y = 40

-2x + 2y = 20

These are set up so we can just add them for the solution:

5y = 60

y = 12

2y-20=2x

x=y-10=2

Answer: x=2, y=12

3(-n+4)+5n=2n <br> a. n=3<br> b. no solution<br> c. infinitely many solutions
777dan777 [17]

Answer:

no solutions

Step-by-step explanation:

3(-n+4)+5n=2n

Distribute

-3n +12 +5n = 2n

2n+12 = 2n

Subtract 2n from each side

12 = 0

This is never true so there are no solutions

5x+5y=0 <br> -8x+y=36<br> I need help with this.
zvonat [6]
First because 5x+5y=0 you can factor the 5
from equation so:
5(x+y) =5 (0) => x+y=0
and by solving for × using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing × into the "x+y=0" equation so we get:
-4+y=0 => y=4

<h3>Answer:  Choice C)  -3m^12n^6</h3>

Explanation:

The coefficients -24 and 8 divide to -24/8 = -3. Based on this alone, the answer is between choices B and C.

The m terms divide to \frac{m^5}{m^{-7}} = m^{5-(-7)} = m^{5+7} = m^{12}

Notice how I subtracted the exponents. The general rule is \frac{a^b}{a^{c}} = a^{b-c}

Since we get m^12, this points us to choice C as the final answer

For the sake of completeness, here's what the n terms divide to

\frac{n^4}{n^{-2}} = n^{4-(-2)} = n^{4+2} = n^{6}
