Answer:

The simplified expression would be: -6.3n + 8.6

Step-by-step explanation:

First is to write out the expression:

3.6 - 4.3n - 2n + 5

Then re-sort the expression:

-4.3n - 2n + 5 + 3.6

-4.3n - 2n =  -6.3n

5 + 3.6 = 8.6

Your final expression would be:

Please help me find y and show work/steps. I don't know how to do it
trasher [3.6K]

We will check if y and 60cm are parallel.

If the lengths 28cm, 56cm and 15cm, 30cm are in proportion, then y and the segment 60cm are parallel.

\dfrac{56}{28}=\dfrac{30}{15}\\\\2=2\qquad CORRECT!

OK. We know: y and 60cm are parallel. Therefore we have equation:

\dfrac{y}{28+56}=\dfrac{60}{56}\\\\\dfrac{y}{84}=\dfrac{15}{14}\qquad|\text{cross multiply}\\\\14y=15\cdot84\qquad|\text{divide both sides by 14}\\\\y=90cm

<h3>Answer: y = 90 cm.</h3>
