the answer would be 0.3125
Answer:
1
Step-by-step explanation:
3x+5=8
Group like terms
3x=8-5
3x=3
Divide both side by the co-efficient of x which is 3
3x/3=3/3
x=1
So the formula for that is:
(total - difference) ÷ 2 = smaller number
(total + difference) ÷ 2= larger number
In this case, Judy is more so we do second fomula:
(12 + 6) ÷ 2 = 9 hits homerun
and Marnie will hit 12 - 9 = 3 hits
Answer:
They're both proportional because everything's moving at a constant rate. Think of it this way: If a car travels for 50 miles per hour and the speed never changes, it's proportional. If that car at hour 1 traveled at 50mph and then at hour 2 traveled at 60mph, it would be nonproportional since the speed is increasing and changing.
