So,

In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.

LCM of 8 and 7: 56

Multiply each fraction by the appropriate form of 1:
$\frac{3}{8} * \frac{7}{7}\ AND \ \frac{6}{7} * \frac{8}{8}$

$\frac{21}{56}\ AND\ \frac{48}{56}$

We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.

The correct option is B.

The third one

Step-by-step explanation:

It can't be the first one since the peak is 4 since it is the highest

It can't be the second one because the data is all different

It could be the third one since their are gaps

And It can't be the fourth one because the range is 7

So it must be the third one

a. y=3

b.x=-3

c.z=4

d. y=4.33

Step-by-step explanation:

a.Solution:

-32÷8×2+2+1

=-4×2+2+1

=-8+2+1

=-8+3

=-5

b. Solition:

53×9+109×53

=477+5777

=5300

c. Solution:

-891

d. Solution:

-63×12+12×37

=-756+444

-312

a. Solution:

5y-3+3=-18+3

5y=-15

y=-15/5

y=3

b. Solution:

-3x-9+9=0+9

-3x=9

x=9/-3

x=-3

c. Solution:

4+3-3(z-8-3)=-23-3

4(z-5)=-20

4z-20=-20

4z-20+20=-20+20

z=4

d. Solution:

1-2+2(y-4+2)=5+2

3(y-2)=7

3y-6=7

3y-6+6=7+6

3y=13

y=13/3

y=4.33
