What is 1/4+3/8+1/2+5/8+7/8

Mathematics
1 answer:
Vadim26 [7]3 years ago
6 0

Answer:

2⅝

Step-by-step explanation:

You must convert each fraction to a <em>common denominator</em>.

The <em>least common multiple</em> of 2, 4, and 8 is 8.

  1/4  +3/8  + 1/2  + 5/8 + 7/8     Convert to a common denominator

= 2/8 + 3/8 + 4/8 + 5/8 + 7/8

= (2   + 3     + 4    + 5     + 7)/8

= 21/8                                        Convert to a mixed number

= (16 + 5)/8

=  2  +  ⅝

= 2⅝

Fill in the blank to make the expression a perfect square:
tigry1 [53]

Answer:

64

Step-by-step explanation:

So here you're just completing the square. the equation you gave is simply: n^2+16n+c where c is the unknown value we're solving for. Whenever you complete the square, you add (b/2)^2

The reason for this, is because whenever you write a binomial as a perfect square it's in the form: (x+b)^2 and this binomial expands out to become: x^2+2bx+b^2

If we write the second term of the binomial as b/2 we get:

(x+\frac{b}{2})^2=x^2+2(\frac{b}{2})x+(\frac{b}{2})^2

which simplifies to:

(x+\frac{b}{2})^2=x^2+bx+(\frac{b}{2})^2

and as you can see the last term is (b/2)^2, which is why we need to add that part for it to be a perfect square.

So we would need to add (16/2)^2 = 8^2 = 64

This way, we can express it as a perfect square binomial: (n+8)^2 which expands out to: n^2+2(8)(n)+8^2 = n^2+16n+64

-4x - 28y=56 4x + 14y=-28
ddd [48]
Adding the 2 equations will eliminate x because -4x + 4x = 0
so we get
-14y = 28
y = -2
plug this into the second euqtion:-
4x + 14(-2) = -28
4x  - 28 = -28 
x = 0

answer is x = 0 , y = -2
