3x+3y−z−7

Step-by-step explanation:

"Let's simplify step-by-step.

4x+2y−z−(x−y+7)

Distribute the Negative Sign:

=4x+2y−z+−1(x−y+7)

=4x+2y+−z+−1x+−1(−y)+(−1)(7)

=4x+2y+−z+−x+y+−7

Combine Like Terms:

=4x+2y+−z+−x+y+−7

=(4x+−x)+(2y+y)+(−z)+(−7)"(Mathpapa)

Cynthia completed 2\3 of her to do list in the morning and finished 1\8 of the items during lunch yet lunch break what traction

il63 [147K]

Answer:

Step-by-step explanation:

Alright, lets get started.

In the morning Cynthia completed the work = $\frac{2}{3}$

During her lunch break, she completed = $\frac{1}{8}$

So, she completed total of her work : $\frac{2}{3}+\frac{1}{8}$

So, we need to add these two fractions.

First making common denominator , so

$\frac{16}{24}+\frac{3}{24}$

So, adding = $\frac{19}{24}$

It means she had finished $\frac{19}{24}$ fraction of het to do list. : Answer

Hope it will help :)
