N= -6
put n-6 divided by 3 in a fraction and multiply by 3 to cancel out the denominator and then multiply -4 by 3 to get -12. you should now get n-6=-12 so you now should add the -6 over to the other side making you get n=-6.

-8x+2y=-2 4x+4y=-4 What is the solution to the system

pickupchik [31]

The solution to system is x = 0 and y = -1

Solution:

Given system of equations are:

-8x + 2y = -2 ----------- eqn 1

4x + 4y = -4 ---------- eqn 2

We have to solve the system of equations

We can solve the equations by elimination method

Multiply eqn 2 by 2

8x + 8y = -8 ------ eqn 3

Add eqn 1 and eqn 3

-8x + 2y = -2

8x + 8y = -8

( + ) ---------------

0x + 2y + 8y = -2 - 8

10y = -10

Divide both sides by 10

y = -1

Substitute y = -1 in eqn 1

-8x + 2(-1) = -2

-8x - 2 = -2

-8x = -2 + 2

x = 0

Thus the solution to system is x = 0 and y = -1

Explain how you would use fraction bars to find the quotient of 10/12 ÷ 4/6. What is the quotient?

mylen [45]

(10/12) / (4/6)...when dividing with fractions, flip what u r dividing by, then multiply

10/12 * 6/4 = 10/8 which reduces to 5/4 or 1 1/4
