What is the value of x in the solution to the this system of equations: y=-1/2x + 2
y - 2x = -3

x = 2

Step-by-step explanation:

For system of equations, you need to equal them to each other. First, you need to isolate y on one side of the equation in

Now, equal the equations to each other:

Add to both sides of the equation:

Subtract add 3 to both sides of the equation:

Divide on both sides of the equation. Remember: when you divide a fraction, you multiply by the reciprocal. See below:

Check your work:

-1 = -1

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
