4 : 6.4 as a fraction <br> I need help!
grin007 [14]

Decimal to Fraction = 6 2/5

6.4 as a fraction = 32 /5

Percentage = 640%

Description =

The answer for this question will be 32 /5 because you asked that 6.4 as a fraction. If your asking to convert 6.4 to a fraction then the answer will be 6 2/5 in a mixed number.

Hope this helps.

So I need help with number 3 but if you want to help me with any other number 3 you can I wouldn’t mind
kondor19780726 [428]

Answer:

3.) -x+4

4.)3/4x+3

5.)-3/5(x) -3

6.)-2x + 5

these are the "Slope intercept" forms of 3,4,5 and 6 you can learn to graph them as its hard for me to explain.

Step-by-step explanation:

3.) x+y=4, we want to write this in terms of y, so lets subtract x from both sides

y = -x+4 ----> this is in "slope intercept form" you can learn about this on "khan academy" as well.

4.) 3x-4y=-12 again we write in terms of y, subtract 3x from both sides.

-4y = -3x -12 then since we want y separately, we divide both sides by -4

y = 3/4(x) + 3 ------> if you didnt understand fully what i did to get to that, i divided everything by -4, and hopefully you know that a minus and a minus (multiplied or divided) will give a positive number.

5.) 3x+5y=-15 again we rewrite for y

5y = -3x - 15

y = -3/5(x) -3

6.) 2x+y = 5

y = -2x +5

the form in which y = whatever, is considered "slope-intercept form"

I cant really graph the points for you but watch this video, its very informative: https://www.khanacademy.org/math/algebra/two-var-linear-equations/graphing-slope-intercept-equations/v/graphing-a-line-in-slope-intercept-form
