What is the greatest common factor of the expression 63r^2t^3+42r^3t^5

Question 4 options:

10r^3t^5

21r^2t^3

7r^2t^3

3r^5t^8

Answer is 21r^2t^3

**Answer:**

<em><u>**x= 2.25**</u></em>

<u><em>**y=6.5**</em></u>

**Step-by-step explanation:**

2x+5y=37 <u><em>y</em></u>=11-2x

2x+5(11-2x)=37

2x+55-10x=37

-8x+55=37

-55 -55

-8x=-18

÷-8 ÷-8

<em><u>**x= 2.25**</u></em>

<u><em>y</em></u>=11-2x

<u><em>y</em></u>=11-2(2.25)

<u><em>y</em></u>=11-4.5

<u><em>**y=6.5**</em></u>
