Use the work shown which expression is equivalent to
algol [13]

Answer:

\frac{1}{3} y - \frac{7}{5}x + \frac{2}{3} - \frac{2}{3} y - \frac{4}{9}

Step-by-step explanation:

We are to find the expression which is equivalent to;

-\frac{2}{3}y - \frac{3}{5} x + \frac{2}{9} - \frac{4}{5}x + \frac{1}{3}y

Putting the like terms together we get;

-\frac{2}{3}y + -\frac{2}{3}y - \frac{3}{5} x - \frac{4}{5}x + \frac{2}{9}

Simplifying this gives;

-\frac{1}{3}y - \frac{7}{5}x + \frac{2}{9}

The equation that is equivalent to this answer from the choices is;

\frac{1}{3} y - \frac{7}{5}x + \frac{2}{3} - \frac{2}{3}y - \frac{4}{9}

613.715 rounded to the nearest unit
SpyIntel [72]

Answer: 614

Step-by-step explanation:

Rounding to the nearest unit means to find the nearest integer to a given number.

Step 1: re write the number as

613 + 0.715 to see that 613. 715 is between

613 and 614, since 0.715 is more 613 but not up to 614. Also, the decimal 0.715 is greater than 0.5, therefore, we round up, please note that if decimal is less than 0.5, we round down.

Therefore, 613.715 rounded to the nearest unit is 614.
