I'm not entirely sure but I think this is how you solve it:

surface area is basically just the area of the of surface, so the rectangular prism has 6 sides, surfaces, areas, with different lengths, and you need to find the area of the different areas, so first, the top and bottom, (3 by 10) so that would be 60, then, the two wide sides, (20 by 10) so that would be 400, and then lastly the two thin sides, which is 3 by 20, so that would be 120, now you add all the stuff together, 60 plus 120 plus 400 which is 580, so the surface area would be 580 all around. I hope this made sense. :// goodluck

Surface area: 580 cm

Multiply.

- $\frac{1}{9}$

multiply the numerators and multiply the denominators

- $\frac{2}{3}$ × $\frac{1}{6}$

= $\frac{-2(1)}{3(6)}$ = - $\frac{2}{18}$ = - $\frac{1}{9}$

(33+37+41)=111

111/3=37

She can make 37 scarves

Someone please convert this equation to slope intercept form: 2x - 3y = 6?

IgorLugansk [536]

Slope y-intercept form is: y=mx+b

All you have to do is rearrange the equation:

2x-3y=6
2x=6+3y
2x-6=3y

now divide both sides by 3
(2x/3)-(6/3)=(3y/3)

and it becomes
$y= \frac{2}{3}x-2$ x

Bonus: you can plug in any two values for x and y and you can see both equation gives the same answer!
