I believe you solved for x, but did not plug it back into 7x-35 to get that segment’s length. The correct answer is 49.

Answer:

M; BM = 49

Step-by-step explanation:

The vertical mark between A and M and the vertical mark between M and B show that segments Am and MB are congruent. That makes point M the bisector of segment AB.

The two segments AM and MB are congruent, so their lengths are equal.

4x + 1 = 7x - 35

Subtract 7x from both sides.

-3x + 1 = -35

Subtract 1 from both sides.

-3x = -36

Divide both sides by -3.

x = 12

BM = 7x - 35 = 7(12) - 35 = 84 - 35 = 49

Answer: M; BM = 49

Ticket for football final selling well, on Thursday 4/7 of the tickets are sold, on Friday 1/4 of the tickets are sold, What fra

sergij07 [2.7K]

Answer:

5/28

Step-by-step explanation:

1/1 represents the whole amount of tickets.

4/7 are sold on Thursday.

an additional 1/4 are did on Friday.

fraction of available tickets on Saturday are therefore

1/1 - 4/7 - 1/4 = 4/1 - 16/7 - 1/1 = 28/1 - 16/1 - 7/1 = 5/1

that means out of 28 equal parts of the total number of tickets 16+7 = 23 parts have been sold.

so, there are only 5 out of the total 28 parts available on Saturday, and the fraction of available tickets is therefore 5/28.

we could have also tried to bring both fractions to the same denominator, and found that this is 28.

and then

4/7 + 1/4 = 4/4 × 4/7 + 7/7 × 1/4 =

= 16/28 + 7/28 = 23/28

and the whole is 28/28.

so we have 28/27 - 23/28 = 5/28 left.

surprise, surprise, it is the same result ...
