LuckyWell [14K]
<h2>The answer is "-\frac{8}{9} \\\\".</h2>

Given:

\to \frac{2}{5}n+3-\frac{7}{10}n=\frac{3}{5}-3n

To find:

n=?

Solution:

\to \frac{2}{5}n+3-\frac{7}{10}n=\frac{3}{5}-3n\\\\\to \frac{2}{5}n-\frac{7}{10}n+3n=\frac{3}{5} -3\\\\\to n(\frac{4-7+30}{10})=\frac{3-15}{5} \\\\\to n(\frac{-3+30}{10})=\frac{3-15}{5} \\\\\to n(\frac{27}{10})=\frac{-12}{5} \\\\\to n=\frac{-12}{5} \times \frac{10}{27} \\\\\to n=-4 \times \frac{2}{9} \\\\\to n=-\frac{8}{9} \\\\

Therefore, the final answer of n is "-\frac{8}{9} \\\\".

Evaluate 0.67y + 4 when y = 2 and when y = -2
jarptica [38.1K]

Answer:

2.66 and 4.34

Step-by-step explanation:

To evaluate, substitute the values of y and solve.

So, when y =-2

0.67y + 4 = -1.34 + 4 = 2.66

And when y = 2

0.67y + 4 = 1.34 + 4 = 4.34

Hope this helps.
