Answer:

B

Step-by-step explanation:

Given

\frac{3x}{4} + \frac{2x}{3} = 51

Eliminate the fractions by multiplying through by the lowest common multiple of the denominators 4 and 3

The lowest common multiple of 3 and 4 is 12

12 × \frac{3x}{4} + 12 × \frac{2x}{3} = 12 × 51

9x + 8x = 612

17x = 612 ( divide both sides by 17 )

x = 36 → B

Which expression shows how 8•54 can be rewritten using the distributive property ?
konstantin123 [22]

The distributive property is a(b+c) = ab + ac or a(b-c) = ab - ac

So here are some potential answers:

8(50 + 4) = 8·50 + 8·4


8(60 - 6) = 8·60 - 8·6


I prefer the first answer
