First Answer and Last Answer are correct.

The two middle should be reconsidered, you can't really tell if they are technically Perpendicular.

So the correct answer should be "Can't be determined" for the middle two.

1. Lines AB and CD are both perpendicular to the line EF, then AB || CD (parallel).

2. The relation between lines CD and GH cannot be defined, because the diagram doesn't contain any information about angles at which these lines intersect (or any data about parallelity GH to EF or IJ).

3. The relation between lines AB and GH cannot be defined, because the diagram doesn't contain any information about angles at which these lines intersect (or any data about parallelity GH to EF or IJ).

4. Lines IJ and CD are perpendicular (IJ⊥CD) because they intersect each other at right angle.

I am thinking of a number such that 6 less than the product of 7 and this number is 85 which number is she thinking of
Artemon [7]
6 less than the product of 7 and this number is 85.
6 less than (the product of (7 and this number)) is 85.

6 less than (the product of 7 and x) = 85
6 less than (7 * x) = 85
(7 * x) - 6 = 85

Now you solve! Make sure that whatever you do to one side you also do to the other:
7x - 6 = 85
7x - 6 + 6 = 85 + 6
7x = 91
7x /7 = 91 /7
x = 13

Hope this helps! :)

Audrey reads 14 pages a day and Lauren reads 7 pages a day. If Audrey is on page 56,on what page is Lauren?
Papessa [141]

Answer:

Hey!

Your answer is that Lauren is on page 28!

Step-by-step explanation:

This is because is Audrey reads 14 pages and Lauren reads only 7 that means Audrey is reading twice as much as Lauren..

So if Audrey has read 56 pages, to find how much Lauren has read, divide 56 by 2 which gives you 28

so Lauren has read 28 pages...

HOPE THIS HELPS!!
