\dfrac{4}{5}n-\dfrac{3}{5}=\dfrac{1}{5}n\ \ \ \ \ |multiply\ both\ sides\ by\ 5\\\\4n-3=n\ \ \ \ |add\ 3\ to\ both\ sides\\\\4n=n+3\ \ \ \ |subtract\ n\ from\ both\ sides\\\\3n=3\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{n=1}

Answer:

The correct result would be n = 1.

Step-by-step explanation:

4/5n - 3/5 = 1/5n     /*5n

4 - 3/5 * 5n = 1

4 - 3n = 1

4 - 1 = 3n

3 = 3n

n = 1

For the given expression, which whole number (w) will make the expression true? 5/6
Sonja [21]

Answer:

D. 7

Step-by-step explanation:

The question is incomplete. Here is a possible complete question

For the given expression, which whole number (w) will make the expression true? 5/6 < w/6

A. 3

B. 4

C. 5

D. 7

Given the inequality expression:

5/6 < w/6

Cross multiply

5×6 < 6×w

30<6w

Divide both sides by 6

30/6 = 6w/6

5<w

Reciprocate both sides(this will change the sense of the inequality)

1/5>1/w

Cross multiply

w > 5×1

w>5

This shows that the value of w is a value greater than 5 but not 5. According to the option, the only value greater than 5 is 7. Hence the whole number (w) that will make the expression true is 7
