.
B)
Convert 3 \8 and 6\ 7 to fractions with a common denominator.

Eliminate

D)
Find a number between 3 and 6 to get the numerator and add 8 and 7 for the denominator.

Answers

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:
(3)/(8) * (7)/(7)\ AND \ (6)/(7) * (8)/(8)

(21)/(56)\ AND\ (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.

Answer:

D


Step-by-step explanation:

Since the linear equation for x. -4.8(6.3x-4.18) = -58.56What does x equal?

Please help me! I will give branliest answer! Thank you!

Answers

-4.8(6.3x-4.18)=-58.56
(-4.8)(6.3x)+(-4.8)(-4.18)=-58.56
-30.24x+20.064=-58.56
-20.064 from both sides
-30.24x=-78.624
divide both sides by -30.24 to get x by itself
-30.24x/-30.24=-78.624/-30.24
x=2.6
