Suling bought 3meters of ribbons she used 5/6meter to make a bow find the length of the ribbon left
Ostrovityanka [42]
Subtract the portion used from the whole.

= 3 m - 5/6m
must have common denominators
= (3*6)/(1*6) - 5/6
= 18/6 - 5/6
= 13/6 m
= 2 1/6 m

ANSWER: 2 1/6 meters left

Hope this helps! :)

What is the sum of all values of m that satisfy 2m (squared) -16m+8=0?
vodomira [7]
<h2>Steps:</h2>

So for this, we will be completing the square to solve for m. Firstly, subtract 8 on both sides:

2m^2-16m=-8

Next, divide both sides by 2:

m^2-8m=-4

Next, we want to make the left side of the equation a perfect square. To find the constant of this perfect square, divide the m coefficient by 2, then square the quotient. In this case:

-8 ÷ 2 = -4, (-4)² = 16

Add 16 to both sides of the equation:

m^2-8m+16=12

Next, factor the left side:

(m-4)^2=12

Next, square root both sides of the equation:

m-4=\pm \sqrt{12}

Next, add 4 to both sides of the equation:

m=4\pm \sqrt{12}

Now, while this is your answer, you can further simplify the radical using the product rule of radicals:

  • Product rule of radicals: √ab = √a × √b

√12 = √4 × √3 = 2√3.

m=4\pm 2\sqrt{3}

<h2>Answer:</h2>

In exact form, your answer is m=4\pm \sqrt{12}\ \textsf{OR}\ m=4\pm 2\sqrt{3}

In approximate form, your answers are (rounded to the hundreths) m=7.46, 0.54

Step-by-step explanation:

2x+y=4                  4x+2y=8

2x     =/2                     2y= /2

y=2                          4x=4

If r=9, b=5, and g=6. what does (r+b-g)(b-g) equal?
Alecsey [184]

(r+b-g)(b-g)

I this question , we have the values of r,b and g given , which are r=9,b=5,g=6

And we have to find the value of the given expression . And for that we need to substitute the values of r,b and 9 in the expression. That is ,

(9+5-6)(5-6) = 8(-1) = -8

So the value of the given expression is -8.
