Two fractions have a common denominator of 8 which of these could be two fractions 1/2 and 2/3 and 1/4 1/2

Anna007 [38]

Hi

Fractions that have a common denominator of 8, would be fractions that have denominators that, when multiplied, equal 8.

8/2 = 4
8/3 = 2.7
So the first option is incorrect.

8/4 = 2
8/2 = 4
The second option is correct.

The correct answer is 1/4 and 1/2

Hope this helps! :)

Solve 3x + 23 + x = 7. x = −4 x = 4 x = −0.25 x = 0.25

Hello! So...

We are given the following:

Solve for x.

$3x+23+x=7$

====================

1. Group the like terms.

$3x+x+23=7$

====================

2. Add similar elements ( $3x+x=4x$ ).

$4x+23=7$

====================

3. Subtract 23 from both sides.

$4x + 23 - 23 = 7 - 23$

====================

4. Simplify.

$4x=-16$

====================

5. Divide both sides by 4.

$\frac{4x}{4} =\frac{-16}{4}$

====================

6. Simplify.

$x=-4$ (aka. Option A)

====================

Hope this helps!
