T=tables
b=booths

t+b=27

8t+4b=140

solve

8t+4b
divide both sides by 4
2t+b=35

we have
t+b=27
2t+b=35
it should be obvious that the answer is 8 but using math

multipl first eqution by -1 and add to second

-t-b=-27
<u>2t+b=35 + </u>
1t+0b=8

t=8
sub
t+b=27
8+b=27
minus 8 both sides
b=19

T + b = 27.......t = 27 - b
8t + 4b = 140

8(27 - b) + 4b = 140
216 -8b + 4b = 140
-8b + 4b = 140 - 216
-4b = -76
b = -76/-4
b = 19....19 booths

Mr. Beebe asks the question in lines 6-7 ("Does . . .
shusha [124]

Correct option is D. Mr. Beebe asks the question in lines 6-7 ("Does . . .

quietly") primarily in order to note an apparent inconsistency.

Mr. Beebe sounds cynical (though he says he is not) of the fact that Lucy Honeychurch is someone who plays the piano beautifully and likes to live quietly. He believes that one these both qualities will 'mingle'. In the given context, it seems like Beebe believes that a person can not be both: good at music and like to live quietly. He thinks that it is reflects an inconsistency in Lucy's personality. Thus D is the best answer.

The lines of passage were -

Does it seem reasonable that she should play piano so wonderfully, and live so quietly? I suspect that someday she shall be wonderful in both. The water-tight compartments in her will break down,

Consider the system of equations, x - 2y = 8 and -2x+4y=-16.
sammy [17]

Answer:

y = x/2 - 4    slope-intercept form

y = x/2 + 4   slope-intercept form

NO SOLUTION.

The graph is a pair of parallel lines one line through point (0, -4) and the other through point (0, 4)

Step-by-step explanation:

x - 2y = 8 and -2x+4y=-16.

we can easily convert these to slope intercept form

x - 2y = 8

-2y = 8 - x

2y = x - 8

y = x/2 - 8/2

y = x/2 - 4    slope-intercept form

------------------------------

-2x + 4y = 16

4y = 2x + 16

y = 2x/4 + 16/4

y = x/2 + 4   slope-intercept form

We have 2 lines that are parallel because they have the same slope
