Answer:

Step-by-step explanation:
Three feet make a yard, so 2 yards is 6 feet
If we divide the top (numerator) and the bottom (denominator) by 2 we get
÷
= 
70+70= 140 points gained minus 145 points lost or 140 - 145= -5 points.
<span>The simplified form of the following expression: (8r to the power of -5) minus 3, is (8r^-5) - 3.
Your final answer is (8r^-5) - 3.</span>
