n the same test. What is the average of the two classes combined?

Use ((85x25)+(22x87))/ 47 for this to get the answer of about 86 (rounded)
Add the two averages together and then divide it by 2. Thats your answer.

QR = LN, so
-2x = -3y + 3
OP = VW, so
-6x =-6y + 18
(-2x = -3y + 3)*(-2) ------> 4x = 6y - 6
-6x = - 6y + 18
4x = 6y - 6
<u>-6x = - 6y + 18</u>
-2x = 12
x= - 6
v = -20
you may replace v with -20 and simplify to vertiy the answer.
