This problem comes from subtract mixed numbers
5 3/4 - 2 5/12
7 1/5 - 3 7/10
11 2/3 - 8 1/2

Answers

To convert a mixed number to an improper fraction, multiply the denominator by the whole number out front, then add the numerator. Keep the denominator. For example:

12 1/2 = 2 * 12 + 1 = 25/2
9 1/4 = 4 * 9 + 1 = 37/4

Multiply 25/2 by 2/2 to have a common denominator:
25/2 * 2/2 = 50/4

50/4 - 37/4 = 13/4 or 4 1/3

Answers

Answer:

5.667 yards of fabric was used to make a cape

Step-by-step explanation:

(Total Yard of Fabric)1/3 = (What's Used)

Total Yard Fabric = 17

What's Used = x

1 third = 1/3

(17)1/3 = x

x = 17/3 or about 5.667 yards of fabric used

Double Check:

5.667/17 = 0.3334 which is about 1/3

If you want to find how much he has left:

1 - 1/3 = 2/3

17(2/3) = x

x = 34/3 or about 11.333 yards of fabric left.

Double Check:

11.333/17 = 0.6666 which is about 2/3

What is Quadratic equation?

The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of:

ax² + bx + c = 0

where x is the unknown variable and a, b and c are the constant terms.

You have the quadratic function

f(x) = 2x² + 2x + 4 ,

and remember that all quadratic functions are parabolas opening at point called the vertex.

Since you can plug any real number in our parabola here, its domain is all the real numbers, and this is true for all the quadratic functions of the form ax² + bx + c = 0.

Thus, in interval notation the domain of the function  is (-∞, ∞).

If you chose to use substitution to solve this system what should your equation look
like?
y=5x-5
y= -4x+22

Answers

Substitution-

Step-by-step explanation:

y=5x-5

y= -4x+22

1- use y=5x-5 solve for y (here you don't really have to do anything)

       This stays the same, Therefore y = 5x-5

2- you will substitute y=5x-5 for y in y= -4x+22. The problem should now look like this:

               5x-5= -4x+22

Solving for x

now, with the equation above you will solve for x-

5x-5= -4x+22         (add 4x to both sides)

9x-5= 22               (add 5 to both sides)

9x=27                   (divide by 9)

x=3

Solving for y

Now that you Know that x=3 you can substitute x=3 for x in y=5x-5. The problem should look like this:

                                                    y= 5(3)-5

Now with the equation above you can solve for y

y= 5(3)-5              (multiply 5 by 3)

y= 15-5                 (subtract)

y=10

Now you have your answers X=3  Y=10

Answers

Answer:

(7m-6n)(7m-6n)

Step-by-step explanation:

Given the expression 49m²-84mn+36n², this can also be written as;

49m²-84mn+36n²

= 7²m² - 84mn + 6²n²

= (7m)²-2*7m*6n+ (6n)²

= (7m-6n)²

= (7m-6n)(7m-6n)

Hence the expanded form is  (7m-6n)(7m-6n)
