Which is the correct label of the parallel lines?

liq [111]

Answer:

a ∥ b

Step-by-step explanation:

The symbol "∥" means parallel lines.

Taking a look at the figure above, we have 2 parallel lines, labelled a and b.

A and B are two points on line "a", forming segment AB. However, segment AB is part of line "a".

Same applies to line "b", which has 2 points forming segment CD.

Therefore, the correct label if the parallel lines is a ∥ b

1/4 + 23/28 - 1 please help

AnnZ [28]

Answer:

$\frac{1}{14}$

Step-by-step explanation:

$\frac{1}{4} + \frac{23}{28} - 1 = ?$

First off, let's change everything to a common denominator. This will allow us to add the fractions!

To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.

Let's change the first fraction into a number with a denominator of 28!

$\frac{1}{4} * \frac{7}{7} = \frac{7}{28}$
