61/28+a=19/4a-11/7
Clear the fraction by multiplying by the lcd. The lcd for 28, 4, and 7 is 28 (Since 7 and 4 are factors of 28)
(6/28)·28=6/1 or 6
a·28=28a
(19/4)·28=19·7=133
(11/7)·28=11·4=44

6+28a=133a-44
Combine like terms:
6=105a-44
50=105a
Isolate the a: 50/105÷5=10/21
a=10/21 :)

Question is: how many 84s will fit in 5376? Let's think about some easy multiples:

84 * 100 = 8400, so it's too big
84 * 10 = 840, so it might work

84 | 5376 | 10
       -840

84 | 4536 | 10
       -840

84 | 3696 | 10
       -840

84 | 2856 | 10
       -840

84 | 2016 | 10
       -840

84 | 1176 | 10
       -840

84 | 336

We can't fit any more 840 in 336, so we check how many 84s are in 336 and what's the remainder:

84 | 336 | 4
     - 336

So there's no remainder. Now we add all the partial quotients to get the final result:

10 + 10 + 10 + 10 + 10 + 10 + 4 = <u>64

</u>
It's correct, I checked it with calculator. I just hope you'll be able to read something from that, it's quite difficult to do partial dividing with no pencil and paper :)

The circle with center O has two chords AC and EF which are of same length 9.07.

OD and OB are the two perpendiculars drawn from the center O to the two chords AC and EF .It represents the distance of the chords from the centre.

The circle theorem states: congruent chords are equidistant from the center.

OD is congruent to OB.

Option A is the right answer.

HELP PLEASE Rajiv has a liability on his car. How is this BEST demonstrated?
Dennis_Churaev [7]

He has insurance in case of an accident.

Insurance, in legal and financial terms, is a form of risk management, used primarily to protect against the risk of potential financial losses.

Ideally, it is defined as the fair transfer of risk of potential loss from one entity to another in exchange for a reasonable fee. In practice, however, the insurance protection business often results in litigation between the parties concerned.

Generally, it is a contract in which one party agrees to pay for the financial losses of another party as a result of a specified event.
